What type of enclosures are compatible with the QCL1020?

This breaker is designed for installation in Eaton Quicklag enclosures and OEM control panels. It utilizes a unit mount, bolt-on configuration rather than plugging into a standard load center bus.

What is the recommended terminal torque for the QCL1020?

For the 14-10 AWG wire accepted by this breaker, the recommended terminal torque is 20 in-lbs. Always verify the exact torque specifications printed on the side of the breaker before installation.

What is the modern replacement for the legacy QCL1020?
