That's a shallow derating curve; the breaker doesn't lose much headroom as the enclosure heats up. That's the heat each unit dumps into the cabinet at full load, and it adds up fast in a multi-circuit panel. ## What the breaking capacity numbers tell you Breaking capacity drops as system voltage climbs: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. At typical 400/415 V distribution, 52.5 kA handles most secondary-side faults.","metaTitle":"Siemens 3VA1025-3ED32-0BH0 SENTRON MCCB, 25 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA1025-3ED32-0BH0 molded case circuit breaker, 25 A rated at 40 °C, 3-pole, 75.6 kA at 240 V.
