ED23B045L - 45Amp Circuit Breaker

ED23B045L - 45Amp Circuit Breaker

Finding the right replacement circuit breaker shouldn’t mean reworking your entire setup. The Siemens ED23B045L molded case circuit breaker is designed for compatible Siemens ED-frame electrical distribution systems, making it a practical choice for repairs, scheduled maintenance, or replacing a failed breaker. Rated at 45 amps, 3 poles, and 240VAC, it helps protect circuits from overloads and short circuits while allowing you to keep your existing panel configuration. If you're maintaining a legacy electrical system, having the right replacement can save time and eliminate unnecessary modifications. The ED23B045L is built to last and comes equipped with line and load-side lugs, making installation more convenient in compatible applications.

Inside, the breaker uses a thermal-magnetic trip unit that reacts to both prolonged overloads and sudden short-circuit conditions.
