The 100 % N-conductor protection means the neutral pole is switched and protected at the same rating as the phase poles, which is required for 4-wire systems where the neutral carries load current (e.g., 3-phase + N panelboards feeding single-phase loads).","metaTitle":"Siemens 3VA1220-5GF42-0BC0 Circuit Breaker, 55 kA @ 415 V, 2","metaDescription":"Siemens 3VA1220-5GF42-0BC0 IEC frame 250 circuit breaker, 55 kA breaking capacity at 415 V, 4-pole, TM240 trip unit, 200 A, UVR 24 V DC.
