Breaking capacity is the headline here: 121 kA at 240 V, 75.6 kA at 415 V, 25 kA at 440 V, and 11.9 kA at 690 V. The 200 A rating holds flat from 40 °C through 50 °C, then derates to 176 A at 70 °C, so panel ambient temperature matters for sizing. The 4-pole frame takes up 140 mm width on the rail, with a 158 mm height and 70 mm depth — check your enclosure depth before committing. Front IP40 protection means it's splash-safe from the front but not sealed; keep it inside a cabinet for washdown environments. The shunt trip (order code 3VA9688-0BL32 for the release itself) allows remote tripping via a control signal, useful for emergency-stop circuits or load-shedding schemes.","metaTitle":"Siemens 3VA1220-4EF42-0JA0 SENTRON MCCB, 200 A, 4-Pole, 121","metaDescription":"Siemens SENTRON 3VA1220-4EF42-0JA0 molded case circuit breaker, 200 A continuous, 4-pole, TM240 release, shunt trip.
