ED23B050 - 50Amp Circuit Breaker

ED23B050 - 50Amp Circuit Breaker

Keeping an existing electrical distribution system in service often comes down to finding the right replacement components. The Siemens ED23B050 molded case circuit breaker is designed for use in compatible Siemens ED-frame electrical distribution systems, making it a practical solution for maintenance, repairs, or replacing a failed breaker. Rated at 50 amps, 3 poles, and 240VAC, it provides dependable circuit protection against overloads and short circuits while allowing you to maintain your current panel configuration.

Factory-installed load lugs (LN1E100) accept 10 AWG through 1/0 AWG copper or aluminum conductors, making the breaker suitable for a range of wiring configurations commonly found in commercial and industrial facilities. Its standard ED-frame dimensions allow it to fit compatible Siemens equipment without requiring panel modifications, helping make replacement work faster and more straightforward.
