FAQs
Install the EBBRA304 WT40 3 in accordance with NEC/CEC guidelines for hazardous locations. Use proper conduit sizing for a 1-1/2" trade size, ensure the enclosure is mounted to a stable surface, and confirm the Class I/II/III rating with Division 1 and 2 compliance. The unit includes a built-in circuit breaker, which simplifies wiring and reduces field connections.
EBBRA304 WT40 3 is designed as an interlocked receptacle with an enclosed circuit breaker. It provides a secure interlock mechanism and integrated protection, reducing the need for external interlocks or separate protective devices. For applications requiring external control, use compliant interfaces alongside the enclosure while maintaining the integrity of the hazardous-location rating.
This unit meets NEC/CEC standards and is rated for Hazardous/Classified Locations. It carries NEC hazardous ratings across Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III, along with NEMA ratings 3, 3R, 7, 9, 12. These certifications ensure suitability for demanding industrial environments and regulatory compliance.
The receptacle offers 30A amperage with a 40A circuit breaker, configured as three-wire, four-pole. It is rated for 480 Vac / 250 Vdc and uses a 1-1/2" trade size for conduit connections.
