That interrupting rating means it handles high-fault-current scenarios typical in large distribution panels or industrial mains — it clears a short-circuit fault up to 330 kA without failing, protecting downstream equipment. The 250 A frame is thermally rated at 40 °C ambient, and the breaker includes a communication function for integration into a monitored power system. ## Breaking capacity and derating Breaking capacity drops with system voltage: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V. The 690 V figure is low — this breaker is not intended for 690 V mains protection. Continuous current derates above 55 °C: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, 200 A at 70 °C. ## Auxiliary switch and trip alarm The breaker ships with one auxiliary switch and one trip alarm switch (HP design) factory-installed. That gives you a remote status contact for open/closed and a separate contact that signals when the breaker trips on fault. Dimensions: 181 mm height, 105 mm width, 86 mm depth. Maximum power loss is 48 W at rated current, so account for that heat in the enclosure thermal calculation.","metaTitle":"Siemens 3VA2225-7KP32-0AG0 SENTRON MCCB, 250 A, 3-pole","metaDescription":"Siemens SENTRON 3VA2225-7KP32-0AG0 molded case circuit breaker, 250 A continuous, 330 kA at 240 V.
