This is the part you spec for a main feeder or large subfeed in a 400 V to 690 V distribution panel where you need adjustable pickup and time bands to coordinate with downstream breakers. The breaking capacity is substantial: 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V. At 60 °C it derates to 955 A, at 65 °C to 885 A, and at 70 °C to 815 A. ## Trip unit adjustability The ETU320 release gives you an adjustable long-time pickup (Ir) from 1000 A minimum, and instantaneous pickup (Ii) adjustable from 1500 A to 10 000 A. The long-time delay tr is settable between 0.5 and 17 seconds. That range lets you shape the trip curve to ride through motor-start inrush or transformer magnetizing current while still clearing a bolted fault fast. Dimensions are 210 mm wide × 320 mm high × 120 mm deep.","metaTitle":"Siemens 3VA2510-5HL32-0AC0 SENTRON MCCB, 1000 A, 3-Pole, ETU","metaDescription":"Siemens SENTRON 3VA2510-5HL32-0AC0 molded case circuit breaker, 1000 A rated continuous current, 3-pole, ETU320 LI release.
