This MCCB includes phase failure detection and a shunt trip release, making it suited for motor branch circuits where loss of a phase needs to trip the breaker fast. The built-in trip indicator and voltage trigger give the field tech a clear visual and electrical signal on fault events.
Interrupting capacity — where it holds and where it drops
The interrupting capacity is 330 kA at 240 V, 242 kA at 415 V and 440 V, and 187 kA at 500 V. That's serious fault-clearing headroom for most industrial distribution panels. If your system runs at 690 V with available fault current above 3.7 kA, this breaker is not the right choice.
The auxiliary switch block (2 aux + 1 trip alarm) and shunt trip release are factory-integrated, so no field assembly of add-on modules.
