Breaking capacity is the story here: 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. That's a high-interrupting rating for a 250 A frame — it clears a serious fault without cascading upstream, which matters when you're coordinating a distribution board or feeding a transformer. ## Auxiliary release and communication That's a common spec for safety disconnects or emergency-stop chains where you want the breaker to open on loss of control power. No auxiliary switch is fitted on this order code; the UVR is the only internal accessory. This variant includes a communication function for remote status and trip reading. Power loss is 50.5 W maximum.","metaTitle":"Siemens 3VA2225-7KP32-0BA0 SENTRON MCCB, 250 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2225-7KP32-0BA0 molded case circuit breaker, 250 A rated, 3-pole, line protection.
