E 450 priority switches
E 450
E 450 priority switches
The priority switch is used in wiring systems where existing lead cross sections or the size of the
power supply service box do not allow for simultaneous operation of two powerful loads (e.g. storage
heating and flow-type heater).
The priority switch disconnects the long-term load (storage heating) for as long as the short-term
consumer (flow-type heater) is switched on.
The coil of the priority switch is connected in series to the short-term load. When this load is switched
on, the NC contact of the priority switch disconnects e.g. the heating system contactor.

TWS twilight switches
They switch-on and/or switch-off operating illuminating devices at preset level of ambient lighting.
Used in combination with sensor detecting if lighting level is higher or lower than preset threshold.
Versions with built-in time switch allow the control of the lighting plant in relation to the level of ambient
lighting combined with a specific time program.

Additional technical features
RAL overload alarms are equipped with an acoustic alarm which signals an exceeding power consumption, allowing the user to disinsert loads before the energy-limiting circuit-breaker trips.
An appropriate relay output contact allows the choice between the following functions:
a) remote signalling (acoustic or lighting)
b) opening a specific divisional circuit-breaker and then disabling a particular not primary electric
appliance.
If appropriately used, the function b) causes the automatic switchoff of one or more appliances in
order to keep the power consumption within the preset limits, avoiding the unexpected tripping of
current-limiting device installed outside the housing (i.e. in the basement). Reset manually.

LSS1/2 load shedding switches
Main circuit-breaker downstream installed, they compare the higher allowed and preset value of
power consumption to the effective system power consumption avoiding the tripping of the main
circuit-breaker through switching-off in sequence of maximum two not primary loads (NPL1 and
NPL2) when the preset threshold is exceeded. A green LED signals the voltage and two red leds
indicate load OFF. At preset time intervals the device automatically tries to insert again not primary

- phase sequence
- phase failure
- minimum voltage (adjustable up to 70% of Vn).
If one of the three failures is detected, the output relay (safety switching contact) intervenes with a
delay adjustable from 2 to 20 seconds for minimum voltage only and controls the following:
- acoustic alarms
- motor controlling contactors
- circuit-breakers with coils.

Additional technical features
The LEE-230 lamp automatically switches on when the voltage fails; the built-in rechargeable battery guarantees
the supply.
It is particularly useful thanks to its construction and functional characteristics:
– it can be extracted from the socket and used as a torch with ON-OFF button on its frontal side
– when necessary it can work with standard sockets
– it can be moved when it is needed
– it has a long operation endurance, up to three hours
– it is ready to use, it does not require installation
– with a screw (ø 3.5 mm, L 16 mm) it is possible to fix it preventing the extraction from the M1173 ABB sockets
with central hole
– the projecting part of the Schuko profile is very small (8 mm).
The two LEDs placed on the frontal side of the lamp indicate its operation condition:
– the red LED indicates the recharge activity and that, in the case of a network voltage back-out, the lamp will
remain off
– the green LED indicates the recharge activity and that, in the case of a network voltage black-out, the lamp
will switch on (it will automatically switch off when the voltage returns).
By pushing the frontal pushbutton it is possible to change the status; if you do not use the lamp for a prolonged
time it is suggested to set the first condition in order to preserve the battery life.

Max./min. current/voltage relays
RH/RL
Max./min. current/voltage ammetric and voltmetric relays
These devices are used to measure current (ammetric) and voltage (voltmetric) on single-phase
electric networks for a perfect protection of devices used.
The range includes:
• maximum current (RHI) and maximum voltage (RHV) relay. The control relay remains on as long
as the quantity to be measured is lower than the set threshold value;
• minimum current (RLI) and minimum voltage (RLV) relay. The control relay remains on as long
as the quantity to be measured is higher than the set threshold value.
In both cases the relay switches off with a delay adjustable by the potentiometer, which also allows
to adjust hysteresis (from 1 to 45%).

E 235 mains disconnection relays
SK 0171 B 02
E 235 mains disconnection relays
Constant exposure of electrical interference fields originating from live conductors - as is the case
e.g. in bedrooms - may impair the well-being of people, experts say.
With the extra base load adapter E235-GLA, the mains disconnection relays can be switched on
manually.
For the permanent installation of loads that switch on independently of the supply voltage, such as
fluorescent lamps, a E235-GLE PTC base load element is available.

E 236 undervoltage monitoring relays
Function
The green LED is lit when the supply voltage is applied. If each phase voltage exceeds 195 V (US1)
or exceeds the preset threshold value (US2) with respect to the neutral including the hysteresis when
switching the device on, the relay switches immediately into the working position. The yellow LED
is lit. If at least one phase voltage falls below the threshold value, the relay goes back into its normal
position and the yellow LED goes out.
If also phase 2 fails, the green LED goes out, too.
It is indispensable to connect the neutral conductor!
Application
For the control of three-phase undervoltage (each phase to neutral) of switchgear, also for installations
according to DIN VDE 0107 (power installations in hospitals and rooms used for medical purposes
outside of hospitals) and DIN VDE 0108 (power installations and safety supply in buildings where
many people gather).
US 1: 3 phases to neutral with fixed threshold at 195V; hysteresis fixed 5 %
US 2: 3 phases to neutral with fixed threshold at 160 – 240V; hysteresis fixed 5 %
