Quick Summary

Eaton EBBRA104 TT70 3 interlocked receptacle protects equipment in hazardous locations. This solution addresses the common challenge of integrating interlock control with built-in circuit protection, reducing mis-sequencing and downtime. It is engineered to meet NEC/CEC requirements and hazardous-location ratings, including Class I, II, and III, along with applicable NEMA standards. The copper-free aluminum enclosure, spring door, and enclosed breaker combine to simplify installation, improve reliability, and reduce lifecycle maintenance costs while delivering long-term protection for critical processes. In practice, this enables engineers and procurement teams to specify a single, compliant enclosure for motor control and power distribution in harsh environments.

Feature: Explosion-proof interlock with enclosed circuit breaker; Business Impact: Simplifies safety interlock control while ensuring continuous power protection; Application: Hazardous-location panels in chemical processing and oil/gas facilities. The integrated design reduces wiring complexity and potential fault points, accelerating commissioning. Feature: 100A amperage rating with 70A circuit breaker; Business Impact: Supports high motor and load profiles with proper overload protection; Application: Large-gear drives and heavy-duty pumps without separate protective devices. This reduces BOM count and installation time while maintaining code-compliant protection. Feature: 480 Vac / 250 Vdc, Three-wire four-pole configuration; Business Impact: Enables reliable power distribution for dual-voltage systems and complex motor circuits; Application: Mixed-voltage equipment in manufacturing lines. Improves compatibility and ensures safe switching across sources, reducing risk during transfers. Feature: Copper-free aluminum enclosure; Business Impact: Corrosion resistance and lighter weight improve durability and ease of handling in harsh environments; Application: Outdoor or washdown areas where metal compatibility matters. This choice lowers maintenance costs and extends service life. Feature: Spring door with solid door option; Business Impact: Tamper resistance and secure access while maintaining quick field service; Application: Enclosed control panels subject to routine maintenance. The robust door design minimizes wear and provides reliable sealing in demanding facilities. Feature: Area classification and NEC/CEC compliance with multiple NEMA ratings; Business Impact: Ensures regulatory alignment and risk mitigation across hazardous locations; Application: Industries requiring rigorous certification trails, including Class I/II/III environments and hazardous-location approvals. This supports audit readiness and reduces project risk.

FAQs

Plan for a 1-1/2" trade size opening with a solid door option in a copper-free aluminum enclosure. Ensure proper torque on mounting hardware and verify that the location falls under Hazardous/Classified Locations per NEC/CEC. The unit ships with dimensions of 14.06 in length, 24.7 in height, and 10.25 in width to fit standard control panels and enclosures.
This receptacle carries Hazardous/Classified Locations area classification with NEC/CEC standards and NEC hazardous ratings for Class I, II, and III, plus NEMA ratings 3, 3R, 7, 9, and 12. These certifications ensure safe operation in challenging environments, support compliance audits, and reduce the risk of nonconformance in regulated industries.
Yes, the device is rated for 480 Vac and 250 Vdc, designed as a three-wire, four-pole configuration to support dual-voltage motor circuits and control loads. This compatibility simplifies integration with existing equipment and ensures correct switching, protection, and interlock sequencing in mixed-voltage environments.
The interlocked receptacle with a spring/spring-door design provides secure interlock control, reducing accidental resets and misoperation. The built-in enclosed circuit breaker streamlines wiring and maintenance, lowering field service time and improving mean time between failures (MTBF) in hazardous-area installations.
By combining protection, interlock control, and a durable copper-free aluminum enclosure, this unit minimizes parts counts and simplifies installation. Expected benefits include lower maintenance costs, reduced downtime, easier compliance reporting, and longer service life in tough environments, delivering a favorable total cost of ownership for critical industrial applications.
