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.","metaTitle":"Siemens 3VA1112-5EF32-0DA0 SENTRON MCCB, 125 A, 3-Pole, TM24","metaDescription":"Siemens 3VA1112-5EF32-0DA0 SENTRON molded case circuit breaker, 125 A continuous at 40 °C, 121 kA SCCR at 415 V, 3-pole, TM240 release.
