TEF134050 - 50Amp Circuit Breaker

TEF134050 - 50Amp Circuit Breaker

The TEF134050 is a 3-pole, 50 Amp Type TEF molded case circuit breaker used in commercial and industrial electrical distribution systems. It features an 18kA interrupting rating at 480VAC along with a non-interchangeable thermal magnetic trip unit that provides protection against overloads and short circuits. If you're replacing an existing Type TEF breaker, matching the original ratings and physical dimensions is often the first priority, and this breaker is intended to provide that same form, fit, and function in compatible equipment. This breaker comes with load-side lugs, making it ready for installation in the appropriate application. Its molded case design is built to last and helps provide dependable circuit protection in electrical panels, switchboards, and other power distribution equipment. Whether you're performing routine maintenance or replacing a failed breaker, the TEF134050 offers the electrical ratings and compatibility needed to keep existing systems operating as intended.
