It is configured as a starter-protection device with a TM120M thermal-magnetic release — note the TM120M is set for motor-starting duty, not general distribution — and the short-circuit protection trip threshold Ii is adjustable from 5 to 15 times In. ## Deployment context — panel integration The clamp connections accept copper or aluminum conductors; the undervoltage release coil draws from a 208–230 V AC control supply, so verify the control transformer secondary matches that range before wiring.","metaTitle":"Siemens 3VA1163-5MH36-0DC0 Circuit Breaker, 63A, 55kA @ 415V","metaDescription":"Siemens 3VA1163-5MH36-0DC0 IEC frame 160 circuit breaker, breaking capacity class M Icu=55kA @ 415V, 3-pole, TM120M starter protection, 63A, undervoltage release 208-230V AC.
