Above 50 °C it steps down: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, 213 A at 70 °C. Interrupting capacity is the other gate. This breaker clears 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. ## Built-in accessories and wiring The UVR means the breaker drops out when control voltage is lost — common for emergency-stop circuits or safety isolation where a loss of control power should open the main.","metaTitle":"Siemens 3VA2225-7HM32-0DH0 SENTRON MCCB, 250A 3-Pole, 330kA","metaDescription":"Siemens SENTRON 3VA2225-7HM32-0DH0 molded case circuit breaker, 250A rated, 3-pole, 330kA interrupting at 240V.
