It carries a 187 kA interrupting rating at 240 V and 121 kA at 415 V, making it a high-fault-current unit for main or feeder protection in industrial switchboards. The 250 A rating holds at ambient temperatures up to 50 °C without derating; at 55 °C it drops to 238 A, and at 70 °C to 200 A. The 187 kA at 240 V and 121 kA at 415 V tell you this breaker can interrupt very high fault currents typical at the service entrance or near large transformers. At 690 V the rating drops to 5.1 kA, so it is not a primary choice for 690 V distribution without coordination study. Maximum power loss is 48 W. Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep. The 86 mm depth includes the case body; allow extra clearance for the shunt trip (STL) and auxiliary switch wiring. ## Trip unit and accessories The ETU850 is an electronic overcurrent release with communication capability. It supports voltage triggering (yes) and other measurement functions.","metaTitle":"Siemens 3VA2225-5KP32-0KC0 SENTRON MCCB, 250 A, 3-Pole, ETU8","metaDescription":"Siemens 3VA2225-5KP32-0KC0 SENTRON MCCB, 250 A rated, 3-pole, ETU850 electronic trip unit. 187 kA at 240 V.
