CFD63B110L - 110A Circuit Breaker

CFD63B110L 110 Amp 3-Pole Molded Case Circuit Breaker

When your breaker needs to be replaced, the first question is usually whether the replacement matches the equipment already in service. The CFD63B110L is a 110 amp, 3-pole molded case circuit breaker built on the Sentron CFD6 platform and commonly used in commercial and industrial power distribution systems. For applications that require the same frame style, ratings, and connection configuration, it offers a straightforward form-fit-function replacement option.

This breaker features a non-interchangeable trip unit and fuseless current-limiting construction. It carries interrupting ratings of 200kA at 240VAC, 200kA at 480VAC, and 100kA at 600VAC, making it suitable for installations where available fault current levels require substantial interrupting capacity. Both line-side and load-side terminals are included, which can help simplify replacement work in compatible equipment.

Rated for 50/60Hz operation and 40°C ambient conditions, the CFD63B110L is often found in switchboards, panelboards, motor control equipment, HVAC systems, and facility power distribution equipment. Maintenance teams, electricians, and facility managers frequently look for breakers that match the original equipment specifications, and that's where this model is commonly used. Like many molded case circuit breakers built for industrial service, it was made to last and support everyday operation in commercial and industrial environments.
