TEB122050WL - 50Amp Circuit Breaker

TEB122050WL - 50Amp Circuit Breaker

The TEB122050WL is a 2-pole, 50 amp molded case industrial circuit breaker designed for your applications requiring dependable overcurrent and short-circuit protection in 120/240VAC electrical distribution systems. Built on the E150 frame, this breaker features a non-interchangeable thermal magnetic trip unit that provides both inverse-time overload protection and instantaneous response to short-circuit conditions. Its cable-in/cable-out (lug-lug) configuration includes both line-side and load-side lugs, helping you simplify installation in compatible equipment. Built to last, the TEB122050WL is well suited as a form, fit, and functional replacement for existing compatible TEB series breakers in commercial and industrial electrical systems where maintaining original equipment compatibility is essential.
