The Siemens 3VA2225-7KP32-0JC0 is a 3-pole SENTRON molded case circuit breaker rated for 250 A continuous current at 40 °C, with an ETU850 electronic trip unit that supports communication functions — meaning it can talk to a BMS or PLC over the integrated comms bus, not just trip on overcurrent.
The ETU850 is the brains — an electronic trip unit with LSIG protection curves (long-time, short-time, instantaneous, ground fault) that you can adjust via the front interface or remotely through the communication module. No undervoltage release or ground fault monitoring module fitted from the factory, but the basic switch platform (3VA2225-7KP32-0AA0) accepts field-installable accessories.
Above that, it drops to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. Mechanical endurance is 20,000 operations — typical for a 250 A frame in distribution duty, not a frequent-switching application.
