Overview
The GE TED134040WL circuit breaker is a thermal magnetic molded case unit designed for industrial control and power distribution systems. Operating at 480VAC across three poles, it provides 40-ampere protection with an interrupting rating of 18kA at 480V. This E-frame TED-series breaker features feed-thru connections with copper/aluminum line and load lugs, making it suitable for replacement in legacy panels and modern industrial installations.
