THFK236175 **Older Style** - 175Amp Circuit Breaker

THFK236175 **Older Style** - 175Amp Circuit Breaker

The THFK236175 is a 3-pole, 175-amp molded case circuit breaker from the THFK series. Built on the F225 frame, it uses an interchangeable thermal magnetic trip unit and includes load-side lugs. This version features the older style black face, making it a suitable match for many existing installations where maintaining the original breaker style and configuration is important. Rated for applications up to 600VAC, the THFK236175 is commonly found in your commercial and industrial power distribution equipment. The breaker's combination of frame size, trip characteristics, and interrupting ratings makes it a practical replacement choice when servicing compatible switchboards, panelboards, and other distribution systems. Like many breakers from this generation, it was built for long-term use in demanding electrical environments.
