What this MCCB is for
Its 100 A continuous rating and 3-pole construction make it a fit for feeder circuits, main disconnects, or backup protection on 400 V class systems where the interrupting rating at 415 V (154 kA) covers high-fault locations like transformer secondaries or large motor banks.
Breaking capacity across voltage levels
This MCCB carries a 220 kA interrupting rating at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 690 V.
Derating starts at 55 °C (96 A), dropping to 90 A at 70 °C. If the panel runs hot — near a drive cabinet or rooftop installation — the 70 °C figure gives a clear ceiling without guessing.
Integrated accessories and wiring
The auxiliary contact version is 2 form C (changeover) contacts, rated for control circuits up to the insulation voltage of 800 V. No undervoltage release, no ground fault monitoring, no communication module — this is a straightforward line-protection breaker with basic remote-trip capability.
