Product details

At 415 V the rating drops to 52.5 kA, and at 690 V to 7.5 kA, so verify the available fault current at your system voltage.

In a sealed enclosure or near heat sources, use the 55 °C figure (19.2 A) as your design limit.

Auxiliary contacts and release options

The breaker ships with four auxiliary switches (HQ type) for remote status indication — enough to signal open/closed and trip to a PLC or annunciator. There is no undervoltage release, no shunt trip, and no ground-fault monitoring fitted on this variant. The TM210 release is fixed thermal and magnetic; it is not adjustable for time or current. Latching endurance is rated at 15,000 operations.
