The Siemens SENTRON 3VA1080-2ED32-0JC0 is a 3-pole molded case circuit breaker rated for 80 A continuous current (Iu) at 40 °C, with a thermal-magnetic TM210 overcurrent release. It's built for line protection in distribution panels and motor branch circuits, carrying a breaking capacity of 52.5 kA at 240 V and 32 kA at 415 V — enough to handle high-fault utility feeds or large transformer secondaries without cascading upstream. A built-in shunt trip (STL) allows remote tripping from a PLC or emergency-stop circuit, and the two HQ auxiliary switches provide feedback for status monitoring.
The 80 A rating holds flat from 40 °C up to 50 °C, then derates gradually: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C.
The shunt trip release is specified as order code 3VA9688-0BL32 for replacement or initial build.
