The 63 A rated current (In) is set by the TM120M thermal-magnetic release, configured here for starter protection: the thermal element is sized for motor overload curves, and the magnetic short-circuit pickup is adjustable from 5 to 15 times In, giving you a range of 315 A to 945 A instantaneous trip. ## Deployment context — what it connects to The TM120M release is a dedicated motor-protection curve, meaning the thermal element tracks the heating characteristic of a motor winding rather than a generic cable. If you are using this as a motor branch-circuit protector, pair it with a separate overload relay (the description notes 'without overload protection' — the TM120M handles short-circuit only, not running overload).","metaTitle":"Siemens 3VA1163-6MH32-0AH0 Circuit Breaker, 70kA @ 415V, 63A","metaDescription":"Siemens 3VA1163-6MH32-0AH0 IEC 3VA1 frame 160 circuit breaker.
