The overcurrent release is thermal-magnetic type TM240. No communication module, no voltage trip, no ground-fault monitoring — it's a straightforward line-protection breaker for fixed-distribution duty. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a standard 3-pole MCCB footprint for DIN-rail or panel-mount enclosures. Front protection is IP40, so it's fine for indoor switchgear but not washdown areas. The auxiliary trip is a separate order (3VA9608-0BB24), not included in the box.","metaTitle":"Siemens 3VA1120-6EF32-0CC0 SENTRON MCCB, 20 A, 220 kA at 240","metaDescription":"Siemens 3VA1120-6EF32-0CC0 SENTRON molded case circuit breaker, 20 A rated, 220 kA breaking at 240 V, 3-pole, line protection, undervoltage release, current production.
