Panel builders will find the 86 mm depth leaves clearance in shallow enclosures. ## Trip unit and thermal derating It includes a trip indicator and communication function for status monitoring. Above that, it derates: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. If your panel runs hot, factor the derate into your load schedule rather than oversizing the frame. Auxiliary switching includes two auxiliary switches, one trip alarm switch, and one electrical alarm switch — enough for remote status and fault annunciation without an add-on module.","metaTitle":"Siemens SENTRON 3VA2225-5KP42-0AL0 MCCB, 250 A, 4-Pole, ETU8","metaDescription":"Siemens SENTRON 3VA2225-5KP42-0AL0 molded case circuit breaker, 250 A max, 4-pole, ETU850 trip unit. 187 kA at 240 V.
