The interrupting capacity climbs to 187 kA at 240 V, 121 kA at 415 V, and still holds 53 kA at 690 V, which covers most industrial distribution panels and motor control centers without needing a current-limiting fuse upstream. The ETU350 release gives you adjustable long-time (tr) from 0.5 to 17 s and short-time (tsd) from 0.04 to 0.4 s, plus an instantaneous pickup fixed at 10 000 A. That range lets you coordinate selectively with downstream breakers — the short-time delay keeps the main from tripping on a branch fault, which is the difference between a localized outage and a whole-panel blackout. ## Continuous current and thermal derating The breaker carries its full 1 000 A continuously up to 55 °C ambient. At 60 °C it derates to 955 A, at 65 °C to 885 A, and at 70 °C to 815 A. Dimensions are 320 mm high, 210 mm wide, 120 mm deep. The 210 mm width is a standard 8.3-inch footprint for this frame size — it bolts into a panel cutout designed for SENTRON 3VA2 breakers, no adapter plate needed.","metaTitle":"Siemens 3VA2510-5HN32-0KB0 SENTRON MCCB, 1000 A, 187 kA at 2","metaDescription":"Siemens 3VA2510-5HN32-0KB0 SENTRON molded case circuit breaker, 3-pole, 1000 A continuous, 187 kA at 240 V.
