The 50 A rating holds flat from 40 °C up to 50 °C ambient; above that it derates linearly to 45 A at 70 °C. Footprint is 101.6 mm wide by 130 mm tall by 70 mm deep — a standard 4-pole MCCB envelope that fits DIN-rail or screw-mounted backplates. Rated insulation voltage is 800 V, operating range -25 °C to +70 °C, storage from -40 °C to +80 °C.","metaTitle":"Siemens 3VA1150-4GE42-0AA0 SENTRON MCCB, 50 A, 4-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1150-4GE42-0AA0 molded case circuit breaker, 50 A continuous, 4-pole, TM220 trip.

The key difference is the trip unit — the 3VA1150-4GE42-0AA0 uses a TM220 thermal-magnetic trip, while the 3VA1110-5ED32-0AA0 carries a different electronic trip.
