It's a line-protection breaker — meaning it's sized for main feeder or large distribution duty, not motor branch circuit protection. The interrupting ratings are 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V, so it handles high-fault utility feeds without cascading upstream. At 60 °C it drops to 955 A, at 65 °C to 885 A, and at 70 °C to 815 A. The ETU860 trip unit gives you adjustable long-time pickup (Ir) from 0.5 to 1.0 × In, so you can set the 1000 A frame down to 500 A for a smaller feeder without swapping breakers. Short-time delay (tsd) is adjustable from 0.05 to 0.5 s — useful for selective coordination downstream. Power loss hits 123 W at rated current. That's heat that stays in the enclosure, so factor it into your thermal budget — especially if you're packing multiple breakers in a single panel. Dimensions are 210 mm wide, 320 mm high, 120 mm deep.","metaTitle":"Siemens 3VA2510-5KQ32-0BH0 SENTRON MCCB, 1000 A, 187 kA","metaDescription":"Siemens 3VA2510-5KQ32-0BH0 SENTRON molded case circuit breaker, 1000 A rated, 187 kA at 240 V.
