Eaton PKE12-XTP012B Molded Case Circuit Breaker

The Eaton PKE12-XTP012B is a molded case circuit breaker delivered as a single assembly that includes a PKE-XTU-4 trip unit. This pairing identifies the device as a protective circuit interrupter built around the PKE12 frame and the integrated PKE-XTU-4 trip mechanism, forming a compact Eaton MCCB solution. The model designation PKE12-XTP012B signals a specific configuration within Eaton's PKE product family, with the trip unit explicitly listed as PKE-XTU-4. This combination is designed to provide overcurrent protection for electrical circuits, leveraging the PKE-XTU-4 trip unit to manage fault conditions and interrupt current when required. In essence, the product is an Eaton-designed molded case breaker and trip unit pair, intended for use where a PKE-series MCCB is appropriate and compatible within Eaton’s protection device ecosystem.
