It is configured for line protection — meaning it guards the feeder or main bus against overload and short-circuit faults, not downstream branch devices. The interrupting ratings are 121 kA at 240 V, 75.6 kA at 415 V, 25 kA at 440 V, and 11.9 kA at 690 V, which covers most industrial distribution panels up to 690 V line-to-line. The 140 mm width across four poles means it occupies a standard 4-pole MCCB footprint; no special adaptor plate required for a DIN-rail or bolted bus connection. Verify the bus-bar pitch matches the 4-pole terminal spacing before committing the panel layout. ## Auxiliary and release configuration The integrated auxiliary trip order code is 3VA9608-0BB24, which is the factory-matched trip unit for this breaker. There is no voltage trigger, no communication function, no phase failure detection, and no ground fault monitoring on this variant. The N-conductor protection is set to 100%, meaning the neutral pole is protected at the same rating as the phase poles.","metaTitle":"Siemens 3VA1220-4GF42-0CC0 SENTRON MCCB, 200 A, 4-Pole, 121","metaDescription":"Siemens SENTRON 3VA1220-4GF42-0CC0 molded case circuit breaker, 200 A rated continuous current, 4-pole, interrupting 121 kA at 240 V.
