EE1H020 - 20Amp Circuit Breaker

EE1H020 - 20 Amp Circuit Breaker

The EE1H020 is a 20 amp, single-pole molded case circuit breaker built on the EH1 frame. It’s typically used when you need a direct replacement in an existing panel or distribution setup where the original specs matter. If your system calls for an EH1 frame breaker with a 14k A.I.C. rating at 277VAC, this unit lines up the way it should—no guesswork, no modifications. It’s calibrated for 40°C operation, which covers most standard indoor electrical environments like commercial buildings and light industrial spaces. The size and layout are familiar, so if you’ve worked with this frame before, installation is straightforward. This is the kind of breaker people use to keep systems running as they were originally designed—nothing fancy, just the right fit and function. Like others in its class, it’s made to hold up over time under normal use.
