ED41B050L - 50Amp Circuit Breaker

ED41B050L - 50Amp Circuit Breaker

When you're working with a 277V system and need reliable circuit protection, the Siemens ED41B050L is a straightforward, dependable option. This 50 Amp single-pole molded case circuit breaker is part of Siemens’ well-known ED frame line, making it a familiar fit in many commercial and industrial panels.

It’s commonly used when maintaining or replacing an existing breaker, especially when keeping the original panel layout intact is important. The single-pole design is suited for protecting individual 277V branch circuits, helping you match existing equipment without reworking the setup.

Installation is simple with line and load side lug terminals that accept copper or aluminum conductors within the specified ranges. With a 22kA interrupting rating at 277V AC, it’s intended for systems where available fault current stays within that limit.
