The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V — those numbers govern fault-clearing capability at the service voltage; at 415 V it handles the full 121 kA without upstream cascading, which is the figure most panel builders check for industrial main breakers. The ETU320 electronic trip unit is adjustable: Ir (long-time pickup) from 400 A to 1 000 A, Ii (instantaneous pickup) from 1 500 A to 10 000 A, and tr (long-time delay) from 0.5 s to 17 s. That adjustability lets you tune the curve to cable thermal limits or transformer inrush without swapping the breaker. ## Thermal derating and endurance The breaker holds its full 1 000 A rating 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. Mechanical endurance is listed at 10 000 operations — typical for a fixed-mount MCCB in a main or feeder position where switching cycles are infrequent. Maximum power loss is 123 W, which matters for enclosure heat rise calculations when the breaker is fully loaded. Dimensions: 210 mm wide, 320 mm high, 120 mm deep. That 210 mm width (8.3 in) is the critical panel cutout dimension — verify against your existing busbar or mounting plate layout.","metaTitle":"Siemens 3VA2510-5HL32-0JA0 SENTRON MCCB, 1000 A, 3-pole, ETU","metaDescription":"Siemens SENTRON 3VA2510-5HL32-0JA0 molded case circuit breaker, 1000 A, 3-pole, ETU320 release, 187 kA at 240 V.
