ED23B050L - 50Amp Circuit Breaker

ED23B050L - 50Amp Circuit Breaker

When you’re working with existing Siemens electrical distribution equipment, having the right replacement breaker matters. The Siemens ED23B050L molded case circuit breaker is designed for use in compatible Siemens ED-frame systems, making it a practical choice for maintenance, repairs, and restoring circuit protection in legacy installations. Rated at 50 amps, 3 poles, and 240VAC, it delivers dependable protection against overloads and short circuits while helping you maintain your current panel layout. With both line and load-side lugs included, this model is ready for installations where secure conductor connections are required without additional accessories.

This breaker uses a thermal-magnetic trip unit, which responds to both sustained overload conditions and sudden fault events. That combination helps support safe operation in properly rated systems by addressing different types of electrical disturbances.
