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

Product Overview

This explosion proof junction box is built for hazardous location wiring applications where Class I Division 2 and Class II Division 2 conditions exist. The enclosure includes a built-in motion sensor with on/off functionality, allowing occupancy-based control of connected lighting without requiring a separate sensor housing in the hazardous area.

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. Wall and ceiling mounting positions are both supported.

This product is ETL listed and carries a 5-year warranty.

Where This Product Fits Best

This junction box is rated for use in Class I, Division 2, Groups A, B, C, and D environments where flammable gases or vapors may be present under abnormal conditions. It is also rated for Class II, Division 1, Groups E, F, and G locations with combustible dust, as well as Class II, Division 2, Groups F and G, and Class III environments.

The UL 1598 wet location rating and UL 1598A Marine Outside Type designation make this enclosure appropriate for outdoor industrial sites, waterfront facilities, and marine vessel applications where moisture exposure is expected. ABS certification supports use in shipboard and offshore installations.

Typical environments include petrochemical processing areas, grain handling facilities, paint spray booths, fuel storage perimeters, and other locations where hazardous atmosphere classifications require compliant wiring enclosures.

Performance and Functional Considerations

The integrated motion sensor provides basic on/off switching for connected lighting loads. This is a presence-detection function only and does not include dimming capability.

IP65 ingress protection means the enclosure is sealed against dust and protected from low-pressure water jets from any direction. This supports installation in washdown areas, dusty industrial spaces, and outdoor locations exposed to rain or hose spray.

The compact footprint allows this junction box to fit into tight mounting locations while still providing sufficient internal volume for conductor terminations in hazardous area wiring runs.

Installation and Long-Term Use

The junction box mounts directly to walls or ceilings using the integrated mounting provisions. Conduit connections are made through the knockout openings. The standard 3/8 inch knockout accommodates common small-diameter conduit, while the 1/2 inch knockout option supports larger conduit sizes when required by the installation.

The enclosure construction and IP65 sealing are designed to maintain integrity over years of service in demanding environments. The 5-year warranty covers the junction box and integrated motion sensor components.

How This Fixture Is Commonly Used

Facility operators use this junction box as a transition point in hazardous location wiring systems where occupancy-based lighting control is needed. The built-in motion sensor eliminates the need for a separate sensor enclosure rated for the hazardous area, which simplifies the installation footprint.

In practice, the junction box serves as both a wiring termination point and an occupancy detection device. Lighting connected through this enclosure switches on when motion is detected and off when the area is unoccupied. This is a straightforward on/off function without adjustable dimming levels.

The wall and ceiling mounting flexibility allows placement based on the coverage area needed and the physical layout of the space. Ceiling mounting is common in process areas where wall space is limited or obstructed by equipment.

Safety, Certifications, and Warranty

This junction box is ETL listed and meets UL 844 requirements for hazardous locations. Specific classifications covered include Class I Division 2 Groups A, B, C, D; Class II Division 1 Groups E, F, G; Class II Division 2 Groups F, G; and Class III.

The enclosure is UL 1598 rated for wet locations and carries UL 1598A Marine Outside Type designation. ABS certification confirms suitability for marine and offshore installations.

LED Lighting Supply provides a 5-year warranty on this product.
