Eaton Crouse-Hinds FLB142 WT100 3 Explosionproof Circuit Breaker
The Eaton Crouse-Hinds FLB142 WT100 3 is a heavy-duty, explosionproof thermal-magnetic circuit breaker designed to provide critical service entrance, feeder, and branch circuit protection in hazardous industrial locations. Enclosed in a high-strength copper-free aluminum body, this unit safeguards lighting, heating, appliance, and motor circuits against overloads and short circuits. It serves as an essential safety component for upstream, midstream, and downstream process facilities where flammable vapors, gases, or combustible dusts are continuously present.
Engineered for high performance in demanding field environments, the FLB142 WT100 3 features a semi-cylindrical body design that maximizes structural integrity while keeping total enclosure weight low. The integrated Cutler-Hammer EHD thermal-magnetic breaker operates trip-free via an external handle that can be padlocked in the ON or OFF positions for secure lockout/tagout compliance without compromising automatic interruption under fault conditions. Dual round threaded covers set at an angle allow easy access for fast wiring, while vertical through-feed conduit hubs simplify installation.
