ED43B100 - 100Amp Circuit Breaker

ED43B100 - 100 Amp Circuit Breaker

The ED43B100 molded case circuit breaker is designed to provide dependable circuit protection for commercial and industrial electrical distribution systems. Built on the ED4 frame platform, this 3-pole, 100-amp breaker offers reliable protection against overloads and short circuits while maintaining stable performance in demanding environments. With an interrupting rating of 18k A.I.C. at 480VAC and 65k A.I.C. at 240VAC, the ED43B100 helps safeguard equipment and electrical infrastructure from damaging fault conditions. Its bolt-on mounting design allows for secure installation in compatible panelboards and switchboards, while the included load-side terminals simplify connection and reduce installation time. Rated for 40°C operation and HACR applications, this Sentron-style breaker is suitable for systems that power heating, air conditioning, and refrigeration equipment. The breaker is also approved for reverse feed applications, providing additional installation flexibility when system design requires power flow in the opposite direction.
