THFK236125WL **Older Style** - 125 Amp Circuit Breaker Description
THFK236125WL **Older Style** - 125 Amp Circuit Breaker
The THFK236125WL is a 125-amp, 3-pole molded-case circuit breaker built on the F225 frame and equipped with an interchangeable thermal-magnetic trip unit. Featuring the older style black face, this breaker is commonly used in your existing commercial and industrial electrical systems where maintaining compatibility with installed equipment is important.
Rated for applications up to 600VAC, the THFK236125WL provides overcurrent and short-circuit protection for three-phase power distribution systems. The breaker includes both line-side and load-side lugs, helping you to streamline installation in compatible equipment. Its thermal-magnetic trip mechanism responds to both prolonged overload conditions and high-current fault events, helping protect conductors and connected equipment from electrical damage.
Built for demanding electrical environments, this circuit breaker remains a practical choice for maintenance projects, equipment repairs, and replacement applications where matching electrical ratings and physical configuration matter.
