Eaton Cutler-Hammer EHD2040L 2-Pole Circuit Breaker

The Eaton Cutler-Hammer EHD2040L 2-Pole Circuit Breaker is a 40-amp, 480-volt protective device designed for industrial and commercial electrical distributions, where it automatically interrupts fault currents to protect wiring and equipment. With a 14 kA interrupting rating, it can safely clear fault currents on typical 480 V feeders, helping to minimize damage to downstream components and support reliable system uptime. The two-pole design disconnects both hot legs simultaneously, which is essential for protecting two-conductor portions of three-phase circuits and ensuring safe de-energization when a fault occurs. Cited as EHD2040L within Eaton's Cutler-Hammer lineup, this breaker is suitable for use in distribution equipment where two-pole protection at 480 V is required. Because it carries the exact model designation, EHD2040L, it provides a straightforward replacement option for existing installations that specify Cutler-Hammer EHD devices.
