Eaton Specification Sheet - DBR51742 WT100 3
Interlocked receptacle with enclosed circuit breaker ensures maintenance cannot energize the circuit unintentionally, reducing risk and downtime while meeting rigorous safety standards in hazardous areas. The business impact is measurable: safer handoffs, lower incident costs, and easier regulatory audits in chemical plants, oil facilities, and mining operations. This configuration is ideal for applications requiring reliable power interlock and integrated protection within a single enclosure, streamlining installation and sparing extra components. Spring door receptacle design minimizes dust ingress and protects contacts, improving service life and reducing cleaning frequency in dusty or oily environments. The 100A, 600 Vac, three-wire four-pole setup handles robust loads, supporting large motor starters and feeder circuits without compromising safety. Copper-free aluminum body with brass contacts enhances corrosion resistance in aggressive environments, extending lifecycle and reducing maintenance intervals. With 1-1/2" trade size and a 34 lb frame, the unit is built for rugged installations, providing predictable performance in harsh facilities. Compliance-focused features, including NEC/CEC, Hazardous Locations ratings, and NEMA 3/9/12 protection, help ensure safer commissioning, simplified inspections, and regulatory peace of mind.
