CFD63B125 - 125A Circuit Breaker Description
CFD63B125 - 125A Circuit Breaker
When a circuit breaker needs to be replaced, finding a unit that matches the original specifications can save valuable time during maintenance and repair work. The CFD63B125 is a 125 amp, 3-pole molded case circuit breaker from the Sentron CFD6 series, commonly used in commercial and industrial electrical distribution systems. Designed for applications where compatibility with existing equipment matters, this breaker provides a practical form-fit-function replacement solution for systems already utilizing the CFD6 platform.
With its fuseless current-limiting design and non-interchangeable trip unit, the CFD63B125 is built to help protect electrical equipment from overloads and short circuits while meeting the requirements of demanding power distribution environments. Its interrupting ratings of 200kA at 240VAC, 200kA at 480VAC, and 100kA at 600VAC make it suitable for installations where substantial fault-current capacity is required.
You'll often find breakers like the CFD63B125 serving in switchboards, panelboards, motor control equipment, HVAC systems, manufacturing facilities, and large commercial buildings. Rated for 50/60Hz operation and 40°C ambient conditions, it was designed for everyday use in demanding electrical applications. The included load-side terminals can also help streamline installation in compatible equipment. Built to last, the CFD63B125 remains a dependable choice for maintaining and servicing existing electrical distribution systems.
