The interrupting ratings climb from 187 kA at 240 V down to 52.5 kA at 690 V, so the breaker handles high available fault current on the secondary side of a step-down transformer without needing a current-limiting fuse upstream. ## Auxiliary switches and undervoltage release — what is wired in The trip alarm switch changes state only on a fault trip, not on manual open, which simplifies remote fault annunciation. ## Integration notes — panel fit and thermal management The breaker footprint is 210 mm wide by 320 mm tall by 120 mm deep — a standard 3-pole MCCB form factor for a 1000 A frame. Mounts on a backplate or DIN-rail adapter; the 120 mm depth leaves room behind the panel door for cable lugs and busbar connections. At full load the breaker dissipates up to 332.5 W — account for that heat in the enclosure sizing and ventilation, especially if the panel also houses drives or transformers. ## Rated insulation voltage and what it governs That covers 480 V, 600 V, and 690 V distribution without derating the insulation. The interrupting ratings at 690 V (52.5 kA) confirm it is usable on 690 V industrial grids, not just 400/480 V.","metaTitle":"Siemens SENTRON 3VA1510-5EF32-0BL0 MCCB, 1000 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1510-5EF32-0BL0 molded case circuit breaker, 1000 A at 40 °C, 3-pole, line protection.
