Note the absence of integral overload protection — the TM120M here is configured for short-circuit protection only, meaning a separate motor overload relay must be wired upstream or in the starter assembly. ## Accessories and control wiring Factory-fitted with a shunt trip (STL) rated for 12–30 V DC or 24 V AC 50/60 Hz, plus two auxiliary switches (HQ) and one trip alarm switch (HQ). The shunt-trip coil allows remote tripping from a safety PLC or E-stop circuit; verify polarity on the DC supply before energizing.","metaTitle":"Siemens 3VA1163-5MH32-0HH0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5MH32-0HH0 IEC frame 160 circuit breaker, 55kA breaking capacity @ 415V, 63A, TM120M, shunt trip.
