This variant is configured for starter protection: the TM120M trip provides short-circuit-only protection (no overload function), so it pairs with a separate overload relay ahead of a motor starter. ## What's in the box The order code includes a nut keeper kit (for captive mounting hardware on the panel gland plate) and two auxiliary contacts: one HQ auxiliary switch and one HQ trip alarm switch. These are factory-fitted, so you don't need to order them separately or open the breaker cover.","metaTitle":"Siemens 3VA1163-5MH32-0AF0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5MH32-0AF0 IEC 3VA1 frame 160 circuit breaker, 63A, 55kA breaking capacity at 415V.
