The Siemens 3VA1220-4EF42-0AA0-ZD00 is a 4-pole IEC frame 250 molded-case circuit breaker with a TM240 thermal-magnetic trip unit rated at 200 A continuous (In=200A). It carries a 36 kA breaking capacity at 415 V (class S), meaning it can safely interrupt fault currents up to that level on a 400 V distribution bus without cascading upstream — a key number for panel SCCR compliance. Overload protection is adjustable from 140 A to 200 A (Ir), and short-circuit magnetic pickup is fixed at 5 to 10 times In, so it coordinates with downstream branch breakers in a selective scheme.
