It carries a breaking capacity of 187 kA at 240 V, 121 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V — so at 415 V it can safely interrupt a fault current over 120 kA without upstream damage. At 55 °C it derates to 194 A, at 60 °C to 188 A, at 65 °C to 182 A, and at 70 °C to 176 A. ## Physical fit and auxiliary contacts It ships with four HQ auxiliary switches built in — no separate add-on module needed for status feedback. The N-conductor protection is set to 100% of phase rating, which matters for panels feeding nonlinear loads where the neutral carries full phase current.","metaTitle":"Siemens 3VA1220-5GF42-0AE0 SENTRON MCCB, 200 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA1220-5GF42-0AE0 molded case circuit breaker, 200 A rated current, 4 poles, 187 kA breaking capacity at 240 V.
