ED23B090 - 90Amp Circuit Breaker

ED23B090 - 90 Amp Circuit Breaker

The ED23B090 circuit breaker is a 3-pole, 90-amp molded case circuit breaker designed for use in electrical distribution systems that require dependable branch circuit protection. Built in the ED2 frame type and manufactured in the Sentron style, this breaker is commonly used in commercial and industrial panelboards where a bolt-on mounting configuration is required. It provides a 10k A.I.C. interrupting rating at 240VAC, helping protect electrical equipment and wiring from damage caused by overloads and short circuits. The unit includes load-side terminals for convenient installation and is suitable for reverse feed applications, offering flexibility when working with compatible legacy distribution equipment. Rated for operation in 40°C environments and HACR rated, the ED23B090 is designed to meet the protection requirements often found in HVAC and other heavy-duty electrical systems. Like many molded case breakers of its class, it was built to last and intended to provide consistent circuit protection when properly installed within compatible equipment.
