E42B070 - 70Amp Circuit Breaker

E42B070 - 70Amp Circuit Breaker

When a circuit breaker needs replacement, finding the right match is about more than just amperage. The E42B070 molded case circuit breaker is a 70 amp, 2-pole Type E42 breaker designed to provide the proper form, fit, and function for compatible commercial and industrial electrical systems. Whether you're responding to an unexpected equipment failure or carrying out scheduled maintenance, having a breaker that matches the original specifications can help minimize downtime and simplify the repair process.

Built with a bolt-on design and molded case construction, the E42B070 is intended for applications that require dependable overcurrent protection and compatibility with existing equipment. It features interrupting ratings of 25kA at 240VAC and 18kA at 480VAC, making it suitable for a wide range of power distribution systems. Because it is HACR rated, it can also be used in qualifying HVAC and refrigeration applications where maintaining proper circuit protection is essential.

When maintaining legacy equipment, matching electrical ratings and physical dimensions is often critical. The E42B070 helps support continued operation by delivering the specifications needed for compatible installations without requiring modifications to the existing setup.
