The Siemens 3VA2225-5JQ32-0HL0 is a 3-pole SENTRON molded case circuit breaker rated for 250 A continuous current at 40 °C, with an ETU560 electronic trip unit that provides adjustable overload and short-circuit protection. The communication function allows integration with higher-level monitoring systems, though the specific protocol is not detailed here — confirm compatibility with your BMS or PLC network. Temperature derating is linear 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.
The 3-pole design with line protection version suits feeder and branch-circuit protection in distribution panels, motor control centers, and switchgear assemblies.
