It's a line-protection version — meaning it's designed for feeder and main breaker duty, not motor protection. The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V, so it handles high-fault scenarios on the secondary side of a distribution transformer or at the main switchboard. ## Thermal derating and trip unit At 60 °C it drops to 955 A, at 65 °C to 885 A, and at 70 °C to 815 A. The ETU320 release gives you adjustable long-time pickup (Ir) from 400 A to 1000 A and short-time/instantaneous pickup (Ii) from 1500 A to 10000 A, with time delays tr from 0.5 s to 17 s. That's enough flexibility to coordinate with downstream feeders without a separate relay. Dimensions are 210 mm wide, 320 mm tall, and 120 mm deep — that's 8.3 in by 12.6 in by 4.7 in. It's a three-pole frame, so it occupies one standard MCCB mounting position in a switchboard or panel.","metaTitle":"Siemens 3VA2510-5HL32-0BL0 MCCB, 1000 A, 3-Pole, ETU320","metaDescription":"Siemens SENTRON 3VA2510-5HL32-0BL0 molded case circuit breaker, 1000 A rated current, 3-pole, ETU320 release, 187 kA at 240 V.
