Eaton Specification Sheet - DBR56731 WT70 3
Interlocked receptacle design with a spring door and with-breaker enclosure ensures the circuit cannot energize when the door is open. This delivers immediate safety benefits by preventing accidental starts and reduces arc-flash exposure for technicians during maintenance. Ideal for hazardous-location equipment in chemical plants and oil facilities, this unit supports compliant shutdowns in Class II and Class III environments. Copper-free aluminum enclosure reduces weight while resisting corrosion in tough environments, improving longevity and reducing maintenance costs. Brass contact material provides reliable conductivity under high current, supporting stable performance in demanding installations. The 600 Vac rating and 60A receptacle rating, paired with a 70A circuit breaker, offer robust protection for large loads while maintaining code compliance. A 1-1/2 inch trade size simplifies conduit connections and installation, minimizing field labor. Installation and servicing are streamlined by the spring door design, enabling quick access without compromising enclosure integrity. Compliance with NEC/CEC standards and NEMA ratings 3, 9, and 12 provides a clear regulatory path, reducing project risk and lifecycle replacement frequency.

FAQs
Installation follows the IF 1181 DBR Interlock Receptacle guidelines and NEC/CEC compliance. Begin with power off, mount the unit in a suitable enclosure, and connect the three-wire, three-pole configuration to the 60A receptacle with the integrated 70A breaker. Use the 1-1/2 inch trade size fittings and verify the spring door closes completely before energizing. A qualified electrician should validate hazardous-location requirements and interlock integrity after installation.
The device is rated 60A and 600 Vac, configured as three-wire, three-pole with an integrated 70A circuit breaker. This combination supports high-demand loads while maintaining a robust safety interlock. Brass contact material ensures reliable conductivity, and the copper-free aluminum enclosure reduces weight and corrosion risk in harsh environments, contributing to dependable long-term performance in hazardous locations.
