CFD63B070 - 70Amp Circuit Breaker

CFD63B070 - 70Amp Circuit Breaker

When you're electrical systems depend on consistent circuit protection, having the right replacement breaker matters. The CFD63B070 is a 70 amp, 3-pole molded case circuit breaker from the CFD6 series, designed for use in commercial and industrial power distribution applications. Featuring a Sentron frame design and a non-interchangeable trip unit, this breaker helps maintain the original electrical characteristics required by compatible equipment and installations.

Built with fuseless current-limiting technology, the CFD63B070 is engineered to help protect your electrical systems from the damaging effects of overcurrents and short circuits while supporting the operational requirements of three-phase power systems. Its high interrupting capacity ratings—200kA at both 240VAC and 480VAC, and 100kA at 600VAC—make it suitable for applications where substantial fault current protection is required.

This breaker is commonly found in manufacturing facilities, commercial buildings, processing plants, HVAC systems, and other demanding environments where dependable circuit protection is essential. Rated for 50/60Hz operation and ambient temperatures up to 40°C, the CFD63B070 is built to last and provides the form, fit, and function needed when maintaining existing electrical distribution equipment. Load-side terminals are included to help simplify installation and replacement projects.
