Thermal Overload Relay 5.0A 690V 3 Poles
The ABB TA25DU-5.0 is a thermal overload relay rated at 5.0 amperes and 690 volts with three poles. It protects motors from overheating by interrupting the circuit when current exceeds the set threshold. The unit is supplied new in a single pack.
Suitable for motor protection panels up to 5.0A
This relay suits electricians and panel builders wiring motor starters that require a 5.0 ampere trip setting at 690 volts. It is not for circuits needing a different current rating, a higher voltage class, or electronic overload functions.
5.0 ampere trip current
The decisive specification is the 5.0 ampere thermal trip current. The relay opens its contacts when the motor current reaches this value, so the setting must match the motor full-load current exactly.

Questions about this item
What contactor frame size is required to mount the TA25DU-5.0 relay?
The TA25DU-5.0 is designed for direct mounting on ABB contactors with a 25 A frame size, matching the relay's 25 designation.
Can the 5.0 A relay protect a motor circuit that was previously fitted with a lower-range overload unit?
Yes, provided the motor's full-load current falls within the 5.0 A setting range and the supply voltage does not exceed 690 V.
How do I verify the relay trips correctly after installation?
Press the red test button on the front; the auxiliary contacts should change state, simulating a thermal trip at the 5.0 A setting.
