That 50 A holds steady through 50 °C — only starts to derate at 55 °C (49 A) and reaches 45 A at 70 °C, so in a warm panel you still have headroom. Breaking capacity is the headline: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500/690 V. ## Integration — panel fit and wiring Dimensions are 130 mm height, 101.6 mm width, 70 mm depth — a standard 4-pole MCCB footprint that drops into a SENTRON distribution board or a separate enclosure. The 3VA1110-5ED32-0AA0 is a 3-pole 100 A frame with a TM210 release — higher continuous rating but one fewer pole. If your BOM calls for 4-pole (three phases plus neutral) at 50 A, the 3VA1150-5ED42-0AA0 is the correct fit; the 3VA1110 won't cover the neutral pole. Footprint differs: the 3-pole is narrower. No direct drop-in without rewiring.","metaTitle":"Siemens 3VA1150-5ED42-0AA0 SENTRON MCCB, 50A, 4-Pole, TM210,","metaDescription":"Siemens 3VA1150-5ED42-0AA0 SENTRON molded case circuit breaker, 50 A continuous at 40 °C, 4-pole, TM210 release, 187 kA at 240 V.
