TEB122040WL - 40Amp Circuit Breaker

TEB122040WL - 40Amp Circuit Breaker

The TEB122040WL is a 2-pole, 40-amp molded case circuit breaker designed for use in your electrical distribution systems requiring dependable overcurrent and short-circuit protection at 120/240VAC. Built on the E150 frame, this TEB Type breaker features a non-interchangeable thermal magnetic trip unit that provides protection against both overloads and short circuits. Its cable-in/cable-out (lug-lug) configuration, complete with line- and load-side lugs, simplifies installation in compatible equipment. Designed for form, fit, and functional replacement applications, the TEB122040WL is well suited for maintaining existing electrical systems where matching ratings, dimensions, and configuration are essential. Like many industrial molded case circuit breakers, it is built to provide dependable service over time when installed and maintained according to applicable electrical standards.
