Tripping classes of the thermal overload relays
Standard classes in IEC 947-4-1 are classes: 10 A, 10, 20, 30. The tripping class indicates
according to IEC 947-4-1 the maximum tripping time in seconds under specified conditions of
test at 7.2 times the setting current and specifies tripping and non tripping times for 1.5 and 7.2
times the setting current. Mostly used class is 10 A.

Description
TA thermal overload relays are used with A Line contactors for the protection of
motors having a nominal voltage of up to 600VAC max per UL/CSA (690VAC and
800VDC per IEC).
Product range
• Standard relays:
Types: TA25DU, TA42DU, TA75DU, TA80DU, TA110DU, TA200DU and TA450DU
– TA25 to TA110 and TA200 are directly connected in the motor circuit.
– TA450DU relays are fed through a linear type transformer
• Special construction
Thermal overload relays with different certifications and approvals.
Relays for protection EEx e motors.
Construction and function
• General
Thermal O/L relays and their accessories meet UL, CSA and most other important
international standards (IEC), European standards (EN) and the most important
national standards (DIN-VDE, NFC-UTE, BS, etc.). They meet the certification
and approval directives required throughout the world.
Thermal overload relays are 3 pole. The motor current flows through their bimetals
(1 per phase) which are indirectly heated. Under the effect of the heating, the
bimetals bend, cause the relay to trip and the position of the auxiliary contacts to
change.
The relay setting range is graduated in amps. In compliance with international and
national standards, the setting current is the motor nominal current and not the
tripping current (no tripping at 1.05 x setting current, tripping at 1.2 times setting
current).
The tripping curves (cold or warm starting, 3 phases and 2 phases) are shown on
page 2.14.
The relays are built to be self protecting in the event of an overload until the short
circuit protection device is activated.

Application
Technical data
• All the relays have:
–
–
–
–
–
Free tripping: the resetting button, even if held in, does not prevent tripping of the thermal overload relay in the
event of a fault.
Temperature compensation
Phase failure protection according to IEC 947-4-1: Within the limits of the setting range, a reduced tripping time, and
thus improved motor protection, is obrtained in case of a phase failure.
Tripping class: 10A, for TA relays
Test functions and resetting: see table below.
• Auxiliary contacts
The relays have two built in auxiliary contacts: NC marked 95-96; NO marked 97-98. Both contacts are physically separate
and can thus be used for 2 different circuits (control circuit and indication circuit).

LC terminal blocks can be used to convert standard connections into Faston connections: 2 x 6.3mm or 4 x 2.8mm per pole.
The connections are protected against accidental contact.
The LC30-T has a terminal block for the 3 power terminals and a second for the 4 auxiliary terminals of a TA25DU thermal
O/L relay.
The LC26-B1 has two identical terminal blocks each for 3 power terminals. This block allows the power terminals to be
mounted with two DB25 kits or a TA25DU thermal O/L relay and DB25 kit assembly.
NOTE: According to DIN 46429 part 1 and NFC 20-120 the max. capacity of a Faston connection is 25 A.

To avoid untimely tripping, TA and T thermal O/L relays have been designed to withstand roughly 15 switching operations
per hour with an approximately equal distribution between working and rest cycles.
In these conditions, the motor starting time must not exceed 1 second and the starting current must be lower than or equal
to 6 times the motor In.

Motor Protection — general
It is very important to choose an adequate protective device for the safety of the motor during operation and for its durability.
The efficiency of protection methods varies according to the application. The overview below will help you to choose.
There is no general rule and we are available to advise you for special applications and especially in the case of difficult starting.

Protection efficiency:
Note: Fuses
Fuses do not protect motors against overloads. They are only used to protect installations and lines against short circuits.
❑ unsuitable
To ensure efficient protection of a motor against short circuits, it is advisable to use aM type fuses in association with thermal
OLR relays.
■ very average efficiency
For the selection of fuses or circuit-breakers, refer to the indications given in this catalogue concerning contactors on the one
hand and thermal O/L relays on the other.

In general, fuse protection for direct-on-line starting must be sized as follows:
– aM fuses: choose the fuse rating immediately above the full load value of the motor current.
– gG (gI) fuses: determine the fuse rating immediately above the motor current value and choose the next highest fuse rating.

TA450DU
TA-DU thermal O/L relays are 3-pole with manual or automatic resetting mode selection.
The resetting button can also be used for stopping.
Built-in auxiliary contacts are physically separate and, consequently, can be used in different circuits (control circuit/indication circuit).
Each relay is temperature compensated and ensures phase failure protection.
Protective relays up to size TA75DU are protected against direct contact via the front face. Terminal shrouds are available for TA200DU to TA450DU size relays.
The connecting terminals are delivered in open position with (+,-) pozidriv screws and screwdriver guidance. It is advisable to tighten unused terminal screws.

Tripping classes of the thermal overload relays
Standard classes in IEC 947-4-1 are classes: 10 A, 10, 20, 30. The
tripping class indicates according to IEC 947-4-1 the maximum tripping
time in seconds under specified conditions of test at 7.2 times the
setting current and specifies tripping and non tripping times for 1.5 and
7.2 times the setting current. Mostly used class is 10 A.

Altitude
Characterizes the place of use. It is expressed in meters above sea
level.
Circuits
• Auxiliary circuit – all the conductive parts of a contactor designed
to be inserted in a different circuit from the main circuit and the
contactor control circuits.
• Control circuit – all the conductive parts of a contactor (other
than the main circuit and the auxiliary circuit) used to control the
contactor’s closing operation or opening operation or both.
• Main circuit – all the conductive parts of a contactor designed to
be inserted in the circuit that it controls.
Insulation Class according to NFC 20 040 and VDE 0110
Characterizes adaptation of the devices to ambient temperature and
operating conditions. For given clearances and creepage distances,
a device will have different insulating voltages depending on
insulation classes A, B, C & D. Class C corresponds to most industrial
applications. The devices in this catalog belong to Class C.
Coordination of equipment protections during a short circuit
This is the addition upstream of the contactor and thermal overload
relay of a short circuit (SCPD) protection device such as a circuit
breaker, a fuse with a high breaking capacity or other fuses.
IEC publication 947-4-1 defines coordination Types 1 & 2:
• Type 1 – Coordination requires that, in the event of a short circuit,
the contactor or starter does not endanger persons or installations
and will not be able to operate without being repaired or parts being
replaced.
• Type 2 – Coordination requires that, in short circuit conditions, the
contactor or starter does not endanger persons or installations and
will be able to operate afterwards. The risk of contacts being welded
is acceptable. In this case, the manufacturer must stipulate the
measures to be taken with respect to maintenance of the equipment.
Low Voltage Products & Systems
ABB Inc. • 888-385-1221 • www.abb.us/lowvoltage
Rated operational current Ie
Current rated by the manufacturer. It is mainly based on the rated
operational voltage Ue, the rated frequency, the utilization category,
the rated duty and the type of protective enclosure, if necessary.
Conventional free air thermal current Ith
Current that the contactor can withstand in free air for a duty time of 8
hours without the temperature rise of its various parts exceeding the
maximum values given by the standard.
Cycle time
Cycle time is the sum of the current flow time and the no-current time
for given cycle.
Electrical durability
Number of on-load operations that the contactor is able to carry out; it
depends on the utilization category.
Mechanical durability
Number of no-current operations that a contactor is able to carry out.
Load factor
Ratio of the on-load operating time to the total cycle time x 100.
Switching frequency
Number of switching cycles per hour.
