TFK236070 - 70Amp Circuit Breaker

TFK236070 - 70Amp Circuit Breaker

The TFK236070 is a 70 amp, 3-pole molded case circuit breaker designed for protecting your three-phase electrical systems from overloads and short circuits. Built on the F225 frame, this breaker uses an interchangeable thermal magnetic trip unit that responds to both sustained overcurrent conditions and sudden fault events. It is commonly found in commercial and industrial power distribution equipment where dependable circuit protection is required.

With interrupting ratings of 18kA at 600VAC, 22kA at 480VAC, and 25kA at 240VAC, the TFK236070 is suited for a variety of applications across manufacturing facilities, commercial buildings, and other electrical distribution systems. The breaker includes load-side lugs and is designed to match the form, fit, and function of existing TFK installations, making it a practical choice when your maintaining or servicing established equipment. Its molded case construction is built to last and supports long-term use in demanding environments.
