The clamp-type terminals accept copper or aluminum conductors within the rated cross-section range. The factory-fitted shunt trip (STL) operates on 110–127 V DC or AC 50/60 Hz, letting you integrate remote tripping from a safety relay or PLC output.","metaTitle":"Siemens 3VA1112-5MH36-0JH0 Circuit Breaker, 55kA @ 415V, 125","metaDescription":"Siemens 3VA1112-5MH36-0JH0 IEC frame 160 circuit breaker, 55kA breaking capacity at 415V, 125A, shunt trip, auxiliary switches.
