Rated In of 63 A with a TM120M thermal-magnetic release, but configured for starter protection: the thermal overload element is omitted (no overload protection), leaving only the magnetic short-circuit pickup adjustable from 5 to 15× In. That makes it a magnetic-only breaker for motor short-circuit protection where a separate overload relay handles the thermal trip. The shunt trip (STL) operates on 110–127 V DC or AC 50/60 Hz, letting a remote emergency-stop or PLC output drop the breaker without manual intervention. Clamp terminals accept standard copper conductors without lug kits.","metaTitle":"3VA1163-5MH36-0JH0 Siemens 3VA1 63A MCCB, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5MH36-0JH0 IEC frame 160 MCCB, 55kA breaking capacity @ 415V, 63A TM120M starter protection, shunt trip 110-127V AC/DC, 2 aux + 1 alarm.
