Description
Product Overview
The SKL 1.2µF 450V AC Square Motor Run Capacitor (CBB61 type) is a compact, plastic box-type film capacitor designed to assist with the starting and continuous operation of single-phase fractional horsepower motors.
Housed in a flame-retardant, resin-filled rectangular case, this square-style capacitor delivers low dielectric loss, excellent self-healing properties, and long operating life under continuous duty. It is commonly used as a replacement capacitor in ceiling fans, rangehoods, exhaust fans, and small pump or appliance motors.
