TFJ224125 **Older Style** - 125Amp Circuit Breaker

TFJ224125 **Older Style** - 125Amp Circuit Breaker

The TFJ224125 Older Style Black Face molded case circuit breaker is a 2-pole, 125-amp thermal magnetic circuit breaker designed for use in your compatible industrial electrical distribution systems. Built with a non-interchangeable thermal-magnetic trip unit, this breaker provides dependable overcurrent and short-circuit protection while maintaining proper form, fit, and function for existing equipment. Its F225 line molded-case construction makes it well-suited for facilities that require a replacement breaker that matches original system specifications rather than modifications to the electrical installation.

Rated at 22kA at 480VAC and 25kA at 240VAC, the TFJ224125 is intended for applications where interrupting capacity and dependable circuit protection are essential. This unit includes load-side lugs to simplify installation in compatible panelboards and switchgear. Built to last, it remains a practical solution for maintaining and servicing existing electrical systems in commercial and industrial environments.
