It's a line-protection unit — meaning it's sized for feeder and main disconnect duty, not motor-starting curves. The interrupting capacity hits 187 kA at 240 V and still holds 121 kA at 415 V and 440 V, so it handles high-fault panels without cascading upstream breakers. ## Current derating and temperature Above that it derates linearly — 960 A at 55 °C, 940 A at 60 °C, 920 A at 65 °C, and 900 A at 70 °C. If your panel runs hot or sits near a furnace line, that 70 °C figure is the one you plan around, not the nameplate. That covers remote status and shunt-trip capability without adding field-installed accessories — one less thing to order separately. ## Environmental limits","metaTitle":"Siemens SENTRON 3VA1510-5EF32-0BH0 MCCB, 1000 A, 187 kA at 2","metaDescription":"Siemens SENTRON 3VA1510-5EF32-0BH0 molded case circuit breaker, 3-pole, 1000 A rated current, interrupting capacity up to 187 kA at 240 V.
