That covers most industrial distribution panels where high fault current is a concern — think large motor control centers or transformer secondaries. Above that, it derates linearly: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. The IP40 front protection means it's suited for clean indoor environments; no washdown rating here. Maximum power loss is 48 W at rated current. For a densely packed panel, that's a non-trivial heat source — ensure adequate ventilation or forced cooling if you're grouping several of these breakers together.","metaTitle":"Siemens 3VA2225-5KP42-0AA0 SENTRON MCCB, 250 A, 4-Pole, ETU8","metaDescription":"Siemens SENTRON 3VA2225-5KP42-0AA0 molded case circuit breaker, 250 A continuous, 4-pole, ETU850 trip unit.
