ED23B090L - 90Amp Circuit Breaker

ED23B090L - 90 Amp Circuit Breaker

The ED23B090L molded case circuit breaker is designed for dependable circuit protection in electrical distribution systems that require a 90-amp, 3-pole breaker within the ED2 frame family. Built in the Sentron style format, this breaker is commonly used in panelboards and distribution equipment where consistent overcurrent protection and reliable switching are required. Rated for 10kA interrupting capacity at 240VAC, the ED23B090L helps protect electrical systems from overloads and short circuits while maintaining compatibility with existing ED2 frame installations. This breaker includes line and load-side terminals for straightforward installation and is suitable for reverse feed applications when properly installed. Designed to operate in environments up to 40°C, the ED23B090L is also HACR rated, making it suitable for heating, air-conditioning, and refrigeration equipment circuits. Like many molded case breakers built during this product generation, these units were built to last and remain widely used in established electrical systems.
