CED63B090 - 90Amp Circuit Breaker

CED63B090 - 90 Amp Circuit Breaker

The CED63B090 circuit breaker is a 3-pole, 90-amp, fuseless current-limiting molded case circuit breaker designed for dependable circuit protection in commercial and industrial power distribution systems. Built on the CED6 frame, this bolt-on breaker delivers high interrupting capacity—200kA at 240VAC and 480VAC, and 100kA at 600VAC—making it well suited for applications where substantial fault current may be present. Rated for 40°C operation and HACR applications, the CED63B090 is engineered for consistent performance under demanding electrical conditions. It includes load-side terminals and is suitable for reverse feed installations, providing flexibility when matching form, fit, and function in existing systems. As a current-limiting breaker, it helps reduce let-through energy during short circuits, contributing to the protection of downstream components. Built to last and manufactured to meet industry standards, this unit supports reliable operation in legacy and established electrical infrastructures.
