Single-phase voltage relays
Are used for the protection of single-phase loads, equipment and machiney against un-allowable
mains voltage drops and fluctuations as well as against the consequences of neutral line cut-off.
They can be utilized either as independent switching devices, or as relays operating with a magnetic
starter (contactor). Advantages of the relays are wide voltage operation range and broad range of
adjustable parameters, including autoreclosing time delay settings for the protection of machinery
and installations with long-term transient dynamics, like refrigeration and compressor units.
RN-113
Voltage protection relay
in enclosure for standard
DIN-rail mounting. Provides
protection to any wattage
loads: up to 7.0 kW –
through its own changeover
relay output contacts; over
7.0 kW (32A) – via contactor
of appropriate rated power.
To avoid fault tripping of
the power load in case of
minor and/or short-term
undervoltage a fixed trip delay is envisaged, that is
activated when minimal voltage level threshold (Umin)
value is reached. The principle of measurement of
"running mean" voltage value is being used in present
product line and this ensures highest protection level
with accuracy and reliability of operation.
RN-111M
The newest modification of a panel
board mounted single phase voltage
protection relay. Besides the principal
dedication of protecting load against
voltage surges in the mains, it provides
a number of additional functions:
Multifunctional digital display;
Operation mode selection by dipswitch
The relay incorporates functions of 5
complete devices in one compact case:
Combined
OVER/UNDER-Voltage
protection relay with separate setting of Minimal and
Maximal thresholds;
Minimum voltage protection relay;
Maximum voltage protection relay;
Protection from the consequences of neutral phase loss;
Time delay - autoreclosing after the fault with user
defined time delay (protection from frequent starts or
nuisance tripping);
Compact overall dimensions - 2-ways width casing.
RN-101M
Voltage relay for protection
of a single-phase load against
un-allowable mains voltage
variations at currents of up
to 32A. Quite often user face
with the problem that the load
exceeds 16A value admissible for
standard voltage relays. To avoid
additional costs connected with
installation of a contactor into
the panel board, the single-phase PH-102 voltage
relay was designed for greater currents of up to 32A
(7.0 kW), wall mounted immediately in the proximity
of the load consuming equipment.
The relay is functionally similar to standard
voltage relays for single phase voltage protection.

Three-phase voltage-sensitive relays
Are used for protection of three-phase loads against un-allowable mains voltage variations, phase
loss, phase imbalance, phase coincidence and incorrect phase sequence. They are highly effective for
the protection of any three phase electrical equipment and circuits, including equipment with longterm transient dynamics and electric motor load as well as installations where continuous monitoring
of quality, availability and three phase lines presence of the mains voltage is required, for example in
automatic load transfer panels (ATS-panels).
RNPP-301
RNPP-311M
The relay is designed
for protection of machinery
and circuits which are most
critical to all of the power
supply parameters. It has
6 independent adjustable
settings for the basic
parameters. The benefit of
RNPP-301 is a capability of
operation within two types
of circuits with isolated (3
wire) and solidly-earthed neutral (4 wire) electrical
circuits. The relay provides accurate true RMS voltage
monitoring and control over the full phase switching of a
magnetic starter/contactor terminal contacts. Separate
front panel LED indication pattern for each type of fault.
Use of a complex information processing algorithm
allows to make different decisions depending the type
of a fault and either allow autoreclosing when the power
parameters get back to normal or block further operation
until the service engineer to come for the problem
solution if the fault could not be solved by itself.
The relay is designed for protection
of all the faults that may happen for the
majority of customers. It is budgetary
version of RNPP-301 and has one
combined adjustment for voltage
level thresholds, and possibility to
modify the tripping time delay and
autoreclosing time delay. Front panel
DIP-switches allow to select the
type of the monitored circuit (400 or
415V), and to arrange and combine
different operation modes. Such simplification allowed to
decrease the cost of the product significantly and keep all
most frequently required protection modes. The product
finds broad application in protection of refrigerating units
& compressor, ventilation equipments, etc. The relay is
necessary element of any automatic load transfer panels
as well as power supply control panels. Optionally there
is a possibility of 24V DC power supply for continuous
monitoring in case of power loss (optional function for
client special order).
RNPP-302
RNPP-311
The relay is a multifunctional
programmable controller
providing protection in AC
240/415 or 220/380 Volt,
50Hz circuits. The relay
repeats all RNPP-301 functions
including
the
magnetic
starter/contactor full phase
terminals monitoring. In each
operation mode the user
selects the set of parameters
to be monitored on the front panel. Besides, the relay
is equipped with a digital input that locks the relay
in case of a fault. An additional feature: Three-phase
digital voltmeter that displays actual phase/line voltage
RMS value.
RNPP-311 is a simplified
version of RNPP-301 stated above
and designed for majority of users.
It has one combined setting knob
for Maximal and Minimal voltage
level thresholds and thepossibility to set up different time ranges
for autoreclosing. This protection
relay provides tripping basing the RMS voltage value for
the period and combined indication for all detected faults. RNPP-311 has 2
basic modifications: frequency control and special
algorhythm of output contacts operation. Highly
efficient for the protection of refrigeration, compressor,
ventillation machinery. This RNPP-311 is a necessary
component of different types of ATS switches and power
supply control panel boards.
the level of protection and number of
functions for RNPP-311M is unrivaled!

Multifunctional time delay relays
REV-201 two-channel time delay relay
REV-201 timing relays are designed for providing precise and accurate timing in
different automatic control and regulation panels and circuits; they can also serve as
a key element in controlling complex technological schemes and processes. The relay
is designed in different versions with adjustable power-on delays from 0 sec to 36000
sec (10 hours). IT is capable of switching AC circuits of ~240V/50Hz voltage, and DC
circuits of 24-100V.
The relay can operate in four modes:
Independent channel operation (two relay mode);
Parallel channel operation (one relay with two independent delays mode);
Serial (summing) channel operation;
Switch-back “trigger” (crossed) channel energization schematic (cyclic relay mode). Relays versions are
available with a circuit control relay function that energize channels according to a preset program. The relays
can also find application in star-delta electromotor start switching circuits, in cascade connections. One of the
relay versions (REV-201-5) is used for pre-start alarm system implementation according to the regulations of the
Federal Committee for Industrial and Mining Safety Supervision.
REV-201M multifunctional two-channel time relay
The REV-201M two-channel timing relay combines features of all currently produced
REV-201 relays. It provides the following operation modes for each channel:
Time delay relay;
Pulse relay;
Periodic (cyclic) relay;
Switching control relay (including prestart alarm systems).
The relay can be powered either by 220-240V AC voltage, or by operational supply
of 24V DC. The package dimensions have been reduced to standard 2 ways width. The
relay features high accuracy of the setting stability (error max 1%). Double color LED
indicates the status of the output channels. Another feature is low power consumption
under load, ≤ 1W. Using DIP-switches on the front panel allows to achieve minimum 4 operation algorithms
and a wide range of time settings: from 0 to 36000 sec. Design of the relay allows smooth setting adjustment.
At each channel’s output a group of switchover terminals (one NC, one NO) of 7A capacity is installed.

Single-phase power limiter OM-110
Power limiting relay OM-110 is designed for the continuous control over
active and total power capacity of single phase load. Power measurement
range is from 0 - 20 kW or 0 - 20 kVA. Main function of the OM-110 is cutting
off the power load or part of the excessive load basing the user defined
threshold value for maximal power capacity. As soon as the power capacity by
the power load will return to normal operational range after the detected fault
OM-110 will either turn ON the disconnected load with user preset autoreclosing
time or alternatively will block and prevent turning ON the power load back
in this circuit. Thresholds and settings for rated power, tripping time and
autoreclosing time delay are defined by the user by means of DIP switches
and potentiometer knobs on the front panel. Measurement is being performed
with no disconnection of power load my means of current transformer built in to the case of OM-110.
Main applications for the product are – digital wattmeter to measure active or total power, and power
limiting relay to cut off an excessive power load.
Three-phase power limiter OM-310 (SCADA)
Main functions and basic applications of the Three Phase Power
Limiting Relay OM-310 are as follows:
Total power load cut OFF in case the excessive power consumption
level detected within the user preset time range;
Partial power load cut OFF in case within the user preset
time range the device detects the exceeding of an additional
power threshold setting;
Protection of the equipment and machinery from faults and
consequences of low quality of power supply in electrical circuits;
Measurement and indication of 3 phase power supply parameters: values of acting phase and line voltage;
voltages for positive & negative & neutral sequence; true RMS phase currents; consumed active, reactive
and total load; cos ϕ measurements;
Alarm signalization for the faults;
Remote control over the load – ON/OFF using the interface RS-232/RS485 or alternatively by externally
connected remote switch.
OM-310 provides safe and reliable operation with the power loads from 2.5 kW to 30 kW using it’s
internal built-in current transformers. And in case of connection of standard commercially available current
transformers OM-310 may control and operate with the loads of up to 350 kW including the electrical circuits
with insulated neutral line.
OM-310 provides ultimate protection and control over following faults:
Low quality of power supply voltage (unallowable voltage drops, fluctuations, phase loss, correct phase
sequence control and phase coincidence, imbalance of phase/line voltages);
Over-exceeding of user defined maximal current on any of the phases;
Controls currents of earth leaking to the ground;
Data transmission and operation with the power load, control over main parameters and data exchange
could be realized either through RS-485 MODBUS protocol or using RS-232 interface.
Current control and monitoring relay
RMT-101 Overload relay – Maximal current cut-off relay
The RMT-101 relay is designed to disconnect load with the user preset
time delay when the measured current value exceeds some certain user
defined threshold (independent time delay over current protection). Then with
subsequent autoreclosing time delay it will turn ON the load and start monitoring
the current again. It can also be used for measurement and control over the load
current. Can be used as digital ammeter to monitor actual RMS current. The
measurement process doesn’t interfere the operation of the monitored power
load since it takes place with use of case-integrated current transformer.
RMT-101 allows monitoring the value of current and the load status by means
of digital and LED indicator on the front panel. The RMT-101 relay has two
DIP-switches to select the measurement range: 0-10А with accuracy tolerance
of ± 0А; 0-100А with accuracy tolerance of ± 0.4А and the display mode – actual current/maximum current
indication. The unit keeps the terminals status unchanged if after over current tripping the conductor current
continues to exceed the rated current value. The automatic re-closing/restart relay can be turned off, when
necessary, by switching the tonpot. to ∞ position.
The device can be used as:
Maximal current relay;
Priority load selection relay;
Digital ammeter;
RMT-101 can be used for cutting of part of excessive currents of single phase load in the range from 0 to
24 kVA that is current value of 0 to 100A. This is very useful for various domestic & industrial applications,
especially for load limiting in case of the use of generator back-up or mains.
The rated power values are established in terms of current taking 240 volt as constant. For example,
power of 2 kW will correspond to a current of 8.3A (2000W / 240V).
For ease of calculation please follow the table below: 1 kW = 4.15А

The device does not require any accessories and has built in CT for sensing load (current). It has one relay
output for switching direct load upto 16A or operating contactor for any load upto 100A (24kW). The digital
display acts as indicator for setting values as well as Ammeter.
Healthy Phase Selector
The PEF-301 universal automatic electronic phase switch
(microprocessor-based single phase automatic load transfer device)
The device serves to enhance the power supply reliability for
single-phase consumers, and to protect them from inadmissible voltage
faults and fluctuations. It is designed to supply industrial/ household
single-phase 220-240V/50Hz load from three-phase four-wire mains
3 * 415 + N in order to maintain uninterrupted power supply of essential
single-phase loads and protect them against un-allowable voltage variations
in the mains. Depending on the voltage availability and quality in the main
phase (the priority is set to line 1), the device selects the best healthy
phase and rapidly switches the single-phase load to the phase selected.
When the initial phase voltage parameters are restored, PEF-301 may
switch the load back with the user defined time delay or remain operating
on the line to which it transferred the load. It protects any load up to 3.5 kW – directly by means of the relay
output terminals, over 3.5 kW – via magnetic contactor of appropriate rated power. PEF-301 is widely used
with uninterruptible power systems in such applications as communication and telecommunication, cable TV,
access control systems, countryside and suburban construction, alarm illumination and signalization schemes
and a great variety of other applications.
