Westinghouse DFDN100 Dust-Tight Circuit Breaker Enclosure

The Westinghouse DFDN100 is a robust dust-tight enclosure designed to house circuit breakers, providing reliable protection in industrial environments prone to dust and debris. This model is rated for a maximum of 100 amps at 600V AC or 500V DC, making it suitable for applications such as welding disconnects, motor controls, and general electrical safety switching. Key features include a manual on/off/tripped handle mechanism, UL-listed construction for safety compliance, and a rugged metal housing that ensures durability in harsh conditions. Advantages over similar products include its compact design for easy installation, dust-tight sealing to prevent contamination, and compatibility with Westinghouse type circuit breakers (note: breaker not included in this unit). Benefits include enhanced safety by isolating electrical circuits during maintenance, reduced downtime from environmental protection, and versatility for both AC and DC systems. Drawbacks may include its age-related wear in used units and potential need for retrofitting in modern systems. Based on attached images, this unit is in used condition with minor scratches and labeling (e.g., 'Welding Disc.' and 'M65-4-29' tag), but appears functional with intact internals including line/load terminals and switch mechanism. No attached sensors or controllers noted. Applications span manufacturing, welding shops, and dusty industrial settings.
