E43B080L - 80Amp Circuit Breaker

E43B080L - 80 Amp Circuit Breaker

The E43B080L molded case circuit breaker is designed for dependable circuit protection in commercial and industrial electrical distribution systems that require an 80-amp, 3-pole breaker with reliable interrupting capacity. Built on the E43 frame, this breaker provides consistent protection against overloads and short circuits in equipment operating at up to 480VAC. With interrupting ratings of 18kA at 480VAC and 25kA at 240VAC, it is suitable for maintaining the safe operation of electrical panels and power distribution equipment that rely on properly rated protective devices. Rated for 40°C operation and HACR applications, the E43B080L is commonly used in HVAC-related installations as well as general power distribution. The breaker includes line and load-side terminals, helping ensure proper connections during installation. Like many molded case breakers used in long-standing electrical systems, units in the E43 family were built to last and remain a practical solution when maintaining or servicing compatible equipment.
