TEF134020 - 20Amp Circuit Breaker

TEF134020 - 20Amp Circuit Breaker

Finding the right circuit breaker isn't just about matching the amp rating. The breaker also needs to match the equipment it was built for. The TEF134020 is a 3-pole, 20 Amp Type TEF molded case circuit breaker with a non-interchangeable thermal magnetic trip unit and an 18kA interrupting rating at 480VAC. It's intended for use in compatible commercial and industrial electrical equipment where these specifications are required. This breaker includes load-side lugs, making conductor termination straightforward during installation. Whether you're replacing a breaker during routine maintenance or getting existing equipment back into service, using the correct breaker helps preserve the original design of the electrical system. The TEF134020 is built to last and is intended for applications where a Type TEF breaker with these ratings is specified.
