E42B050L - 50Amp Circuit Breaker

E42B050L - 50 Amp Circuit Breaker

The E42B050L molded case circuit breaker is designed to provide dependable circuit protection in electrical distribution systems that require a 50-amp, 2-pole breaker within the E42 frame series. Built for use in commercial and industrial electrical panels, this breaker helps protect wiring and connected equipment from overloads and short circuits while maintaining proper system operation. With an interrupting capacity of 18kA at 480VAC and 25kA at 240VAC, the E42B050L is suited for installations where consistent protection and compatibility with existing E42-frame equipment are essential. This breaker is HACR rated, making it appropriate for heating, air conditioning, and refrigeration applications. It includes line- and load-side terminals, allowing for straightforward installation or replacement in systems designed for this breaker type. Like many molded case breakers built for long service life, it is constructed to withstand typical electrical and environmental demands found in control panels and distribution equipment operating at 40°C.
