The overload protection band Ir=140A...200A gives you a 30% adjustment range below the fixed rating, and the short-circuit pickup is fixed at Ii=10 x In (2000A). The N conductor is protected at 100%. The 55kA Icu at 415V is the ultimate breaking capacity — the breaker can safely interrupt one fault at that level and still be functional afterward (though you'd replace it after a fault near that magnitude). The 100% N protection means the neutral pole is fully rated and trips with the phase poles — important for 4-wire systems where you can't allow an open neutral.","metaTitle":"Siemens 3VA1220-5GE42-0AA0-ZD00 MCCB, 200A, 55kA @ 415V","metaDescription":"Siemens 3VA1220-5GE42-0AA0-ZD00 circuit breaker, IEC frame 250, 4-pole, 200A, Icu=55kA @ 415V.
