Four poles, line protection version, no ground-fault monitoring or N-conductor protection built in. This MCCB interrupts 76 kA at 240 V AC, 53 kA at 415 V AC, 32 kA at 440 V AC, and 11.9 kA at 500 V AC. The 415 V figure is the one most panel builders will anchor to for European 400 V three-phase distribution; the 240 V rating covers North American 240/120 V split-phase or 240 V delta feeds. Maximum rated operational voltage for DC applications is 500 V. ## Panel footprint and integration Maximum power loss is 42 W, so factor that into thermal calculations for sealed cabinets.","metaTitle":"Siemens 3VM1220-3ED42-0AA0 SENTRON MCCB, 200 A, 4-Pole, 76 k","metaDescription":"Siemens 3VM1220-3ED42-0AA0 SENTRON molded case circuit breaker, 200 A rated current, 4-pole, TM210 release.
