Interrupting capacity runs 187 kA at 240 V, drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 4.5 kA at 690 V — so at typical 480 V distribution levels it clears faults well above most service-entrance requirements. The auxiliary switch configuration is two auxiliary contacts plus one trip-alarm switch HQ. ## Derating and thermal reality At 55 °C it derates to 238 A, at 60 °C to 225 A, at 65 °C to 213 A, and at 70 °C to 200 A — so in a warm panel or outdoor enclosure you must reduce the load or increase the breaker frame size accordingly. Maximum power loss is 48 W. Dimensions are 105 mm wide (4.13 in), 181 mm tall (7.13 in), 86 mm deep (3.39 in).","metaTitle":"Siemens 3VA2225-5KP32-0KH0 MCCB, 250 A, 3-Pole, Line Protect","metaDescription":"Siemens SENTRON 3VA2225-5KP32-0KH0 molded case circuit breaker, 250 A continuous, adjustable 375-2500 A trip, 187 kA at 240 V.
