CED63B040 - 40Amp Circuit Breaker

CED63B040 - 40 Amp Circuit Breaker

The CED63B040 is a 3-pole, 40-amp fuseless current-limiting molded case circuit breaker designed for dependable overcurrent protection in commercial and industrial electrical distribution systems. Built on the CED6 frame, this bolt-on breaker delivers consistent performance in applications requiring high interrupting capacity and secure installation. With interrupting ratings of 200k A.I.C. at 240VAC and 480VAC, and 100k A.I.C. at 600VAC, it is well suited for facilities where fault current levels demand reliable protection. Rated for 40°C operation and HACR applications, the CED63B040 is constructed for long-term service and is engineered to maintain proper form, fit, and function in compatible panelboards and switchboards. Load-side terminals are included, and the breaker is suitable for reverse feed applications, offering flexibility for a range of system configurations. This molded case circuit breaker is built to last and provides the protection required to safeguard wiring, equipment, and connected loads in legacy and existing systems that rely on CED6 frame components.
