ED23B045 - 45Amp Circuit Breaker

ED23B045 - 45 Amp Circuit Breaker

The ED23B045 molded case circuit breaker is designed to provide dependable circuit protection in electrical distribution systems that require a 45-amp, 3-pole breaker within the ED2 frame platform. Built for use in panelboards and distribution equipment that accept Sentron-style bolt-on breakers, this unit helps safeguard wiring and connected equipment from overloads and short circuits while maintaining compatibility with existing electrical infrastructure. With a 10kA interrupting rating at 240VAC, the ED23B045 is suitable for a wide range of commercial and light industrial applications where consistent protection and proper form-fit replacement are essential. The breaker includes load-side terminals for straightforward installation and is rated for reverse feed, offering flexibility in system configuration. Designed to operate in environments up to 40°C, this HACR-rated breaker is commonly used in heating, air-conditioning, and refrigeration circuits as well as general power distribution systems. Like many molded case breakers used in long-standing installations, these units are built to last and provide reliable circuit protection when installed and maintained according to applicable electrical standards.
