Square D KCF24100 is a 2-pole, 100A molded case circuit breaker from the KCF Series, designed for thermal magnetic overcurrent protection in single-phase applications. It is rated for 480V AC with a 65kA interrupting capacity at 480V, utilizing LI (Long-Time and Instantaneous) trip functions for coordinated fault response. The unit features a bolt-on connection, weighs 11 lb, and is built on a K Frame without included lugs, requiring separate specification for wiring connections. This breaker complies with industry standards for industrial power distribution and is suitable for protecting branch circuits in panelboards and switchboards. Typical applications include motor control centers, lighting panels, and general-purpose load centers requiring reliable overcurrent protection.
