The built-in undervoltage release (UVR) operates on 120-127 V AC, so it drops the breaker if control voltage is lost, a common requirement for safety disconnects on conveyor or machine-tool feeds. The 63 A fixed overload protection (Ir = 63 A) and fixed short-circuit protection set at 10 x In (Ii = 630 A) mean this breaker is pre-configured for a specific load — no field-adjustable dials. That suits a design where the load current is known and stable, like a fixed-speed pump or a lighting distribution board. Mounts on standard DIN rail inside an enclosure. The nut keeper kit (included per the order code) holds the terminal screws captive during wiring — a small detail that saves time on a panel build. The UVR coil draws from a 120-127 V AC control circuit; verify the control transformer taps match before energizing.","metaTitle":"Siemens 3VA1063-3ED32-0CA0 Circuit Breaker, 63A, 25kA @ 415V","metaDescription":"Siemens 3VA1063-3ED32-0CA0 IEC frame 100 circuit breaker, 63A, 25kA breaking capacity @ 415V AC.
