THFK236090 **Older Style** - 90 Amp Circuit Breaker

THFK236090 **Older Style** - 90 Amp Circuit Breaker

The THFK236090 is a 90-amp, 3-pole molded case circuit breaker from the THFK series. Built on the F225 frame, this breaker uses an interchangeable thermal-magnetic trip unit to protect against overloads and short circuits in your commercial and industrial power distribution systems. This particular unit features the older-style black-face configuration and includes load-side lugs. Often found in existing switchgear, panelboards, and distribution equipment, the THFK236090 is commonly used as a replacement where matching the original equipment specifications is important. Its combination of a 90A current rating, three-pole design, and interrupting capacities up to 65kA at 240VAC makes it suitable for a wide range of your three-phase electrical applications. Built for long-term service, this breaker remains a practical choice for your maintaining and servicing established electrical systems.
