MCCB for line protection — 125 A continuous, 121 kA SCCR at 415 V
It carries 125 A continuously at 40 °C ambient and holds that rating through 50 °C before a linear derate to 114 A at 70 °C. That SCCR headroom means this breaker can be installed at high-fault locations without cascading upstream — useful when the transformer is close or the service entrance feeds a dense MCC lineup. The UVR drops the breaker when control voltage falls below dropout threshold — no separate shunt-trip wiring needed for emergency-stop circuits that must fail to a safe state.
Footprint and panel integration
No communication module or ground-fault monitoring is fitted on this variant, so the wiring compartment stays uncluttered; the UVR coil terminals and line/load lugs are the only connections.
