ED23B045L - 45Amp Circuit Breaker

ED23B045L - 45 Amp Circuit Breaker

The ED23B045L molded case circuit breaker is designed for dependable circuit protection in commercial and industrial electrical distribution systems that use ED2 frame equipment. With a 45-amp rating and three poles, this breaker provides protection against overloads and short circuits in three-phase applications. Built in the Sentron-style ED2 frame, it offers the correct form, fit, and function required when maintaining or servicing compatible panelboards and switchboards. The breaker carries a 10kA interrupting capacity at 240VAC, helping protect connected equipment by interrupting fault currents within its rated limits. It is HACR rated for use in heating, air conditioning, and refrigeration equipment and is designed for operation in environments up to 40°C. The unit includes line and load-side terminals for straightforward installation and is suitable for reverse feed applications when used according to applicable electrical standards. Like many molded case circuit breakers used in long-standing electrical systems, this unit reflects a design built to last and intended to support reliable operation in established installations.
