The interrupting curve drops to 121 kA at 415/440 V and 75.6 kA at 500 V, so the installed SCCR must be coordinated with the available fault current at the point of common coupling. Lifecycle status is current — this is an active catalog number, not a phase-out or last-time-buy. Panel footprint: 210 mm wide, 320 mm tall, 120 mm deep. The 3-pole body accepts line- and load-side lugs for copper or aluminum conductors. Thermal derating: the 1000 A rating holds through 50 °C ambient. Above that, it steps down — 960 A at 55 °C, 940 A at 60 °C, 920 A at 65 °C, 900 A at 70 °C. For a panel with internal temperature rise, size the continuous load against the derated value at the actual enclosure ambient, not the nameplate 1000 A. Maximum power loss is 332.5 W, which must be factored into the enclosure ventilation calculation.","metaTitle":"Siemens 3VA1510-5EF32-0BC0 SENTRON MCCB, 1000A, 3-Pole, 187k","metaDescription":"Siemens SENTRON 3VA1510-5EF32-0BC0 molded case circuit breaker. 1000A at 40°C, 3-pole, 187kA SCCR at 240V.
