CFD63B090 - 90Amp Circuit Breaker

CFD63B090 - 90Amp Circuit Breaker

The CFD63B090 is a 90 amp, 3-pole molded case circuit breaker built on the Sentron CFD6 frame. It is commonly used in commercial and industrial electrical systems where three-phase circuits require protection from your overloads and short circuits.

This breaker features a non-interchangeable trip unit along with a fuseless current-limiting design. With interrupting ratings of 200kA at 240VAC, 200kA at 480VAC, and 100kA at 600VAC, it can be used in applications where available fault current levels require a breaker with substantial interrupting capacity.

Rated for 50/60Hz operation and 40°C ambient conditions, the CFD63B090 is often found in switchboards, panelboards, motor control equipment, HVAC systems, and power distribution equipment. Included load-side terminals can help simplify installation when your replacing an existing breaker or servicing electrical equipment.

For facilities that still rely on compatible CFD6 Sentron-frame equipment, the CFD63B090 offers a straightforward form-fit-function replacement option. Like many industrial molded case circuit breakers from this product family, it was built for long service life and everyday use in commercial and industrial applications.
