The 200 A rating holds flat from 40 °C up to 50 °C, then derates linearly to 176 A at 70 °C, which matters if this breaker lands in a warm enclosure or near other heat sources in the mill. Breaking capacity is 121 kA at 240 V AC, 75.6 kA at 415 V, 25 kA at 440 V, and 11.9 kA at 690 V. Dimensions are 105 mm wide, 158 mm high, and 70 mm deep — a standard 3-pole MCCB footprint for the SENTRON 3VA platform. It ships with two auxiliary switches (HP type) installed, which can be wired into a PLC or annunciator for breaker status without needing a separate contact block.","metaTitle":"Siemens 3VA1220-4EF32-0AB0 SENTRON MCCB, 200 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1220-4EF32-0AB0 molded case circuit breaker, 200 A continuous, 3-pole, TM240 release.
