Breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V, so it can sit upstream of smaller breakers in a high-fault panel without needing a current-limiting fuse ahead of it. ## Panel fit and derating — what the numbers mean on a real bus At 76.2 mm wide, 130 mm tall, and 70 mm deep, this MCCB fits standard SENTRON panel footprints and accepts busbar connectors from the 3VA accessory range. Above that it derates gradually: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C.","metaTitle":"Siemens SENTRON 3VA1132-5EF32-0JH0 MCCB, 32 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1132-5EF32-0JH0 molded case circuit breaker, 32 A rated, 3-pole, 187 kA breaking capacity at 240 V.
