The TM120M thermal-magnetic trip unit provides starter protection (motor branch circuit), with adjustable short-circuit pickup Ii = 5...15 x In. Note the description explicitly states 'without overload protection' — this unit is configured for short-circuit protection only, relying on a separate overload relay for the motor. ## Deployment and integration The integrated shunt trip (STL) operates on 220-250 V DC or 208-277 V AC, allowing remote tripping from an E-stop or PLC output.","metaTitle":"Siemens 3VA1163-6MH32-0KA0 Circuit Breaker, 70kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-6MH32-0KA0 IEC frame 160 breaker, 70kA breaking capacity at 415V, 63A, with shunt trip.
