ED23B070 - 70Amp Circuit Breaker

ED23B070 - 70 Amp Circuit Breaker

The ED23B070 circuit breaker is a 3-pole, 70-amp Sentron-style molded case circuit breaker designed for dependable overcurrent protection in commercial and industrial electrical distribution systems. Built on the ED2 frame platform, this breaker is commonly used in panelboards and distribution equipment where a bolt-on mounting configuration is required. With a 10kA interrupting capacity at 240VAC, it helps protect electrical circuits from overloads and short circuits while maintaining compatibility with many existing panel systems that rely on ED-frame devices. The breaker is HACR rated, making it suitable for heating, air conditioning, and refrigeration equipment circuits. It includes load-side terminals for straightforward installation and is suitable for reverse feed applications, giving electricians added flexibility when servicing or maintaining legacy electrical systems. Designed for operation in 40°C environments, this breaker provides a dependable form-and-fit replacement for existing installations where ED2-frame breakers are specified. Like many molded case breakers built for industrial service, it is constructed with durable internal components intended to withstand years of normal operating conditions.
