E2050 - 50Amp Circuit Breaker

E2050 - 50Amp Circuit Breaker

When you're replacing a breaker in an existing panel, especially in older or established electrical systems, the goal is usually simple—match the original specs and keep everything operating the way it was designed. The E2050 50 Amp 2-Pole Circuit Breaker is built for that kind of work. It’s a Type E thermal-magnetic breaker designed for systems that require a 50 Amp rating, 2-pole configuration, and 120/240VAC service.

This model is rated for a 10kA interrupting capacity at 120/240VAC, making it suitable for a variety of general replacement applications within its listed ratings. It also includes a non-interchangeable trip unit, which helps maintain the original factory setup of the equipment it’s installed in. With a 40°C temperature rating and included load terminals, it fits cleanly into compatible systems without requiring changes to the panel layout.

In the field, the E2050 is typically used for maintenance and replacement work—especially when electricians or facility teams need to keep existing equipment running without modifying the original electrical design. Matching the correct amperage, poles, and voltage rating helps ensure the system continues to operate as intended.
