TEF124020 - 20Amp Circuit Breaker

TEF124020 - 20Amp Circuit Breaker

The TEF124020 is a 2-pole, 20-amp molded case circuit breaker designed for use in your commercial and industrial electrical distribution systems. It features a non-interchangeable thermal magnetic trip unit, which provides fixed protection against overloads and short circuits. With an interrupting capacity of 18 kA at 480 VAC, this breaker is intended for installations where those electrical ratings are required. This model includes load-side lugs, making installation into compatible equipment more straightforward. If you're replacing an existing Type TEF breaker, the TEF124020 is designed to match the original form, fit, and electrical function. These breakers were built for long service life and remain a practical choice for maintaining existing electrical systems without altering the original equipment design.
