Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V — numbers that put this squarely in high-fault-current plant feeders or transformer secondaries where the available fault current is well above typical 25–65 kA MCCB ratings. Full 1000 A holds through 55 °C ambient; at 60 °C it derates to 955 A, at 65 °C to 885 A, and at 70 °C to 815 A. That's a shallow curve — you lose 18.5 % by 70 °C, not the steeper drop some frames show — so a warm enclosure (say 50–55 °C) still delivers the nameplate current. Max power loss is 123 W, which factors into enclosure cooling calcs. Dimensions: 210 mm wide, 320 mm high, 120 mm deep. Front IP40. ## Communication and monitoring ETU860 release supports communication function and other measurement function. Ground fault monitoring uses summation current formation on L-conductor. Latching endurance is 10 000 cycles mechanical.","metaTitle":"Siemens 3VA2510-5KQ32-0AG0 SENTRON MCCB, 1000 A, 187 kA at 2","metaDescription":"Siemens 3VA2510-5KQ32-0AG0 SENTRON molded case circuit breaker, 3-pole, 1000 A rated current, 187 kA breaking at 240 V, ETU860 release, current lifecycle.
