It is configured for starter protection with a TM120M thermal-magnetic release and an AM (adjustable magnetic) short-circuit release set at 5–15 x In. The unit includes a shunt trip (STL) coil rated for 220–250 V DC or 208–277 V AC and a nut keeper kit. The TM120M thermal element provides motor overload protection (inverse-time curve), while the adjustable magnetic (AM) element handles short-circuit protection; the 5–15 x In adjustment range lets you tune the magnetic trip to match motor inrush without nuisance tripping. The shunt trip (STL) allows remote or emergency-off tripping via a control signal, common in safety circuits and E-stop chains.","metaTitle":"Siemens 3VA1163-5MH32-0KA0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5MH32-0KA0 IEC frame 160 circuit breaker, 63A, 55kA breaking capacity at 415V AC.
