The Siemens 3VA1163-6MH36-0AH0 is a 3-pole molded-case circuit breaker from the 3VA1 IEC frame 160 series, rated 63 A continuous current with a breaking capacity class H — Icu of 70 kA at 415 V AC. The TM120M thermal-magnetic trip unit is configured for starter protection: the thermal element is sized for motor inrush, and the magnetic instantaneous pickup is adjustable from 5 to 15 times In (315 to 945 A), letting you dial it in for the locked-rotor current of the load. This variant ships without overload protection (the TM120M provides only short-circuit and ground-fault protection), so it relies on a separate overload relay upstream or at the motor.
