ED23B040L - 40Amp Circuit Breaker

ED23B040L - 40 Amp Circuit Breaker

The ED23B040L molded case circuit breaker provides reliable overcurrent protection for electrical systems designed for ED2 frame, 3-pole breakers rated at 40 amps. This Sentron-style breaker is commonly used in commercial and industrial distribution equipment where maintaining the correct form, fit, and function is important. With a 10kA interrupting rating at 240VAC, the breaker is built to help protect wiring and connected equipment from overloads and short circuits within compatible systems.

This model includes both line-side and load-side terminals, which helps simplify installation during maintenance or replacement work. The breaker is also suitable for reverse feed applications, offering flexibility depending on panel configuration. Rated for 40°C operation and carrying an HACR classification, the ED23B040L is frequently used in circuits serving heating, air-conditioning, and refrigeration equipment. Like many molded case breakers used in long-standing electrical infrastructure, it is designed with durability in mind and built to last in properly maintained systems.
