Product details

The Siemens 3VA1112-5MH36-0JH0 is a 3-pole IEC molded case circuit breaker on the 160 A frame, configured for motor starter protection without integral overloads — the TM120M release provides magnetic-only short-circuit protection with an adjustable instantaneous trip (Ii) from 5 to 15 times In.

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.
