Explosion Proof Junction Box | 1/2 in or 3/4 in NPT | Wall or Ceiling Mounted | Built-in Motion Sensor | Class 1 Div 1 | Class 2 Div 1

Product Overview

This explosion proof junction box includes a built-in motion sensor with on/off functionality. The enclosure is rated for Class I Division 1 and Class II Division 1 hazardous locations, allowing installation in environments where ignitable gases, vapors, dusts, or fibers may be present during normal operations.

The junction box measures 5.6 x 5.6 x 4.2 inches and ships with a 3/8 inch knockout as standard. A 1/2 inch knockout configuration is available as a special order option. Mounting orientation supports both wall and ceiling installations.

Where This Product Fits Best

This junction box is built for facilities operating under hazardous location classifications where standard enclosures are not permitted. Class I Division 1 coverage includes areas with flammable gases or vapors in Groups C and D. Class II Division 1 coverage extends to combustible dust environments in Groups E, F, and G.

The UL 1598 wet location rating and UL 1598A Marine Outside Type listing make this enclosure suitable for outdoor installations, coastal facilities, and marine applications where moisture and salt exposure are factors. ABS certification supports use in shipboard and offshore environments.

Performance and Functional Considerations

The built-in motion sensor operates as on/off control only. This allows occupancy-based switching of connected lighting loads without requiring a separate sensor enclosure rated for hazardous environments.

IP65 protection means the enclosure resists dust ingress and low-pressure water jets from any direction. This supports reliable operation in washdown areas, dusty processing spaces, and outdoor locations exposed to rain or spray.

Installation and Long-Term Use

The junction box accepts wall or ceiling mounting and includes a 3/8 inch knockout for standard conduit entry. Installations requiring 1/2 inch NPT entry should specify the special order knockout configuration at time of purchase.

ETL listing confirms third-party evaluation for the hazardous location ratings stated. The 5-year warranty covers the junction box and integrated motion sensor components.

How This Fixture Is Commonly Used

In day-to-day operation, the integrated motion sensor activates connected lighting when personnel enter the detection zone and turns it off after the area is vacated. This eliminates the need for manual switching in hazardous areas where minimizing ignition sources is critical.

Facilities using this junction box typically connect it to explosion proof light fixtures in the same hazardous classification. The compact 5.6 x 5.6 x 4.2 inch footprint fits into tight mounting locations common in processing areas, equipment rooms, and walkways within classified zones.

Safety, Certifications, and Warranty

This junction box is ETL listed and carries UL 844 certification for hazardous locations. Specific coverage includes Class I Division 1 Groups C and D, Class I Division 2 Groups A, B, C, and D, Class II Division 1 Groups E, F, and G, Class II Division 2 Groups F and G, and Class III environments.

Additional certifications include UL 1598 for wet locations, UL 1598A Marine Outside Type, and ABS approval. We provide a 5-year warranty on this product.
