What this 3VA1 breaker carries
The Siemens 3VA1163-5MH36-0DC0 is a 3-pole IEC frame 160 circuit breaker in the 3VA1 series, rated 63 A with a breaking capacity class M delivering Icu=55 kA at 415 V AC. 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.
