At 415 V the rating holds at 121 kA, and it still manages 75.6 kA at 500 V, so it covers most low-voltage distribution panels in North American and European installations. At 55 °C it drops to 238 A, at 60 °C to 225 A, and at 70 °C to 200 A. The 86 mm depth and 140 mm width fit standard MCCB mounting footprints in distribution panels; front IP40 protection handles typical switchgear environments.","metaTitle":"Siemens 3VA2225-5KP42-0KD0 SENTRON MCCB, 250 A, 4-Pole, ETU8","metaDescription":"Siemens 3VA2225-5KP42-0KD0 SENTRON molded case circuit breaker, 250 A rated at 40 °C, 4-pole, ETU850 electronic trip unit.
