The interrupting rating reaches 330 kA at 240 V, stepping down to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. At the 400 V class common in industrial distribution, the 242 kA figure gives substantial headroom for high-fault installations — useful when coordinating with upstream transformers or busway.
Protection and auxiliary complement
Built for motor duty, this MCCB includes phase failure detection and a trip indicator. The UVR is a separate auxiliary release, not a voltage-triggered trip unit.
Maximum power loss is 12.5 W.
