The Siemens SENTRON 3VA2063-5KP32-0KL0 is a 3-pole molded case circuit breaker rated for 63 A continuous current at 40 °C, with an interrupting capacity of 187 kA at 240 V and 121 kA at 415 V. The communication function means it can talk to a higher-level system for metering and status — typical for a plant-floor power distribution panel where you want remote trip indication and load monitoring without a separate power meter.
Thermal derating — the real-world current
Above that, it derates: 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C.
Auxiliary contacts and releases
That gives you four discrete signals for the PLC or DCS: breaker open/closed, trip event, and a separate electrical alarm. The shunt trip (STL) release is built in — no separate undervoltage release on this variant. The integrated auxiliary trip module is order code 3VA9688-0BL33.
