The Siemens 3VA1163-4ED36-0KF0 is a 3-pole IEC frame 160 molded-case circuit breaker in the 3VA1 series, with a 63 A fixed thermal-magnetic overload release (Ir = 63 A) and a fixed short-circuit release set at 10 × In (630 A).
Deployment context
The clamp-type terminals accept copper or aluminum conductors up to the rated cross-section for the 63 A frame, and the integrated shunt trip (left-side, 208–277 V AC / 220–250 V DC) allows remote tripping from an emergency-stop circuit or a PLC output — a common requirement in conveyor and pump panels where the breaker doubles as a disconnect under remote supervision.
