Current-carrying capacity derates with ambient temperature: 200 A through 50 °C, then 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. ## Physical Fit & Panel Integration Dimensions: 140 mm wide, 158 mm high, 70 mm deep. The 4-pole footprint matches standard Siemens SENTRON 3VA mounting patterns — direct panel-mount or DIN-rail adapter (not included). The 70 mm depth leaves clearance behind a typical 200 mm deep enclosure gland plate. ## Auxiliary Release & Communication The basic switch supplied is order code 3VA12206EF420AA0.","metaTitle":"Siemens 3VA1220-6EF42-0JA0 SENTRON MCCB, 200 A, 4-Pole, TM24","metaDescription":"Siemens 3VA1220-6EF42-0JA0 SENTRON molded case circuit breaker, 200 A at 40 °C, 4-pole, TM240 thermal-magnetic release, 220 kA at 240 V.
