This variant is configured for starter protection with a TM120M thermal-magnetic release, but note the spec: it provides short-circuit protection only (Ii adjustable 5–15× In), without overload protection. That means it's intended for use ahead of a separate motor starter or contactor that handles the overload function — not as a standalone motor-protective breaker. It ships with two HQ auxiliary switches and one HQ trip alarm switch, plus clamp-type terminals for wiring. The HQ designation indicates high-rupturing-capacity microswitches rated for control-circuit isolation. Mounts on standard DIN rail or panel — typical for IEC distribution boards and machine control cabinets.","metaTitle":"Siemens 3VA1163-6MH36-0CH0 Circuit Breaker, 63A, 70kA @ 415V","metaDescription":"Siemens 3VA1163-6MH36-0CH0 IEC frame 160 circuit breaker, 63A, 70kA breaking capacity at 415V AC.
