It's configured for motor starter protection (TM120M thermal-magnetic release, AM) providing short-circuit protection only — no overload function in this build, so the motor starter's own overload relay handles that job. The adjustable short-circuit pickup range is 5 to 15 times In (315 A to 945 A). ## What's on the breaker A nut keeper kit is also included — that's the hardware that prevents the mounting nuts from backing off under vibration, a detail that matters on a motor circuit in a pump house or compressor skid.","metaTitle":"Siemens 3VA1163-6MH32-0KH0 Circuit Breaker, 63A, 70kA @ 415V","metaDescription":"Siemens 3VA1163-6MH32-0KH0 IEC frame 160 circuit breaker, 63A, 70kA breaking capacity @ 415V.
