CED63B040L - 40Amp Circuit Breaker

CED63B040L - 40 Amp Circuit Breaker

The CED63B040L is a 40-amp, 3-pole fuseless current-limiting molded case circuit breaker designed for reliable circuit protection in commercial and industrial power distribution systems. Built on the CED6 frame, this breaker provides high interrupting capacity—up to 200kA at 240VAC and 480VAC—making it well-suited for installations where available fault current is significant. With included line- and load-side terminals and suitability for reverse feed applications, the CED63B040L offers straightforward form, fit, and functional replacement in compatible panelboards and switchboards. Engineered for use in systems operating up to 600VAC and rated at 40°C, this HACR-rated breaker is built to last and help maintain safe, code-compliant electrical distribution.
