ED43B080 - 80Amp Circuit Breaker

ED43B080 - 80 Amp Circuit Breaker

The ED43B080 molded case circuit breaker is designed to deliver dependable overcurrent protection for commercial and industrial electrical distribution systems. Built in the ED4 frame, Sentron style, this 3-pole, 80-amp breaker helps safeguard equipment and wiring by interrupting overloads and short circuits before damage can occur. Its high interrupting capacity—18kA at 480VAC and 65kA at 240VAC—makes it well-suited for demanding electrical environments where reliability and safety are essential. The bolt-on mounting design provides a secure installation within compatible panelboards and switchboards, while included load-side terminals simplify wiring and installation. Rated for 40°C operation and HACR applications, the ED43B080 is also suitable for reverse feed, offering flexibility for a variety of electrical configurations in modern power distribution systems.
