Breaking capacity drops as system voltage rises: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, 17 kA at 690 V. Maximum power loss is 44.5 W, which factors into enclosure thermal calculations. The SENTRON series carries the usual IEC/UL certifications for molded case circuit breakers; compliance documentation (RoHS, REACH) is available with the shipment.","metaTitle":"Siemens 3VA1220-6EF42-0BH0 SENTRON MCCB, 200A, 220kA at 240V","metaDescription":"Siemens 3VA1220-6EF42-0BH0 SENTRON molded case circuit breaker, 200A rated, 4-pole, 220 kA breaking capacity at 240 V AC.
