CED63B125 - 125Amp Circuit Breaker

CED63B125 - 125Amp Circuit Breaker

When a facility depends on reliable power distribution, having the correct replacement breaker matters. The CED63B125 is a 125 amp, 3-pole molded case circuit breaker designed for use in commercial and industrial electrical systems where matching original equipment specifications is important. Whether you're performing scheduled maintenance, replacing a failed breaker, or servicing existing distribution equipment, this breaker provides the ratings and configuration commonly required in compatible CED6 installations.

Built with a fuseless current-limiting design, the CED63B125 carries interrupting ratings of 200kA at both 240VAC and 480VAC, along with 100kA at 600VAC. It is often found in switchboards, panelboards, motor control equipment, HVAC systems, and other power distribution applications where high fault-current ratings are required. The bolt-on mounting design and included load-side terminals help simplify installation in compatible equipment and make it easier to match existing configurations during maintenance and replacement work.

The CED63B125 is HACR rated and suitable for reverse-feed applications when permitted by the equipment design. Rated for operation in 40°C ambient environments, it is used in manufacturing facilities, warehouses, commercial buildings, schools, healthcare facilities, and other locations that rely on three-phase electrical distribution. Built to last, this breaker provides the form, fit, and function needed for compatible replacement applications in existing electrical systems.
