The 3VA2225-6JP32-0AB0 is a Siemens SENTRON molded case circuit breaker (MCCB) rated for 250 A continuous current at 40 °C, with an adjustable thermal-magnetic trip unit covering 375 A to 2500 A — so it protects feeders and large motor circuits where the full-load current falls inside that band. The interrupting ratings climb with available fault current: 242 kA at 240 V AC, 187 kA at 415/440 V, 121 kA at 500 V, and 4.5 kA at 690 V. Thermal derating is published from 40 °C to 70 °C: the breaker holds 250 A up to 50 °C, then drops to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. It includes a communication function and two HP auxiliary switches pre-installed.
The 250 A continuous rating and adjustable trip make it a fit for large motor circuits, transformer secondaries, or main incomers in sub-distribution boards. The communication function allows remote monitoring and trip indication over a fieldbus, which is useful for facility management systems or data-center power monitoring.
