EH24040 - 40 Amp Circuit Breaker

EH24040 - 40 Amp Circuit Breaker

Keeping your existing electrical system running as intended starts with choosing a breaker that's designed to match the original equipment. The EH24040 is a 2-pole, 40-amp plug-on thermal-magnetic circuit breaker designed as a form, fit, and function replacement for compatible Type EH-4 applications. It helps protect branch circuits by responding to both sustained overloads and instantaneous short-circuit conditions, making it an important part of maintaining safe, reliable operation in compatible electrical distribution systems.

Whether you're replacing an existing breaker during preventative maintenance or restoring equipment after an electrical fault, matching the correct breaker type, amperage, pole configuration, and interrupting capacity is essential for proper compatibility.

Where It Works Best

The EH24040 is well-suited for maintaining compatible commercial, industrial, and institutional electrical systems that require a 2-pole, 40-amp Type EH-4 plug-on thermal-magnetic circuit breaker. It is commonly used to protect 480VAC branch circuits serving HVAC equipment, motor loads, control panels, machinery, lighting systems, and other electrical loads operating within its rated capacity. Before installation, verify that the breaker's pole configuration, amperage, voltage rating, interrupting capacity, mounting style, and Type EH-4 designation match your existing equipment to ensure proper compatibility and a correct form, fit, and function as a replacement.
