It is configured for starter protection with a TM120M release, set at In=63 A, and provides adjustable short-circuit protection Ii=5...15 x In. The unit includes a shunt trip (STL) rated for 220-250 V DC or 208-277 V AC, plus two auxiliary switches (HQ). The TM120M thermal-magnetic release is sized for motor starting duty: the thermal element tracks motor heating while the magnetic pickup (5–15x In) allows the inrush without nuisance tripping. The adjustable Ii range lets you coordinate with downstream devices; set it at 5x In (315 A) for a soft-start motor or 15x In (945 A) for a direct-on-line start with high locked-rotor current. ## Deployment context The nut keeper kit (included per the order code suffix) secures the terminal connections against vibration in industrial environments.","metaTitle":"Siemens 3VA1163-5MH32-0KC0 Circuit Breaker, 55kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-5MH32-0KC0 IEC frame 160 circuit breaker, breaking capacity class M, Icu=55kA @ 415V, 3-pole, In=63A, starter protection TM120M, shunt trip, 2 aux switches.
