Where This Product Fits Best

This junction box is intended for hazardous locations requiring Class I Division 2 and Class II Division 2 protection. It is also rated for Class II Division 1 and Class III environments.

It is suitable for use in facilities where flammable gases, vapors, or combustible dusts may be present under abnormal conditions. The IP65 rating allows installation in areas exposed to dust and water jets.

The product is appropriate for both indoor and outdoor use, including marine environments, due to its UL 1598A Marine Outside Type rating. It can be mounted on walls or ceilings as required by the site layout.

Applications include chemical plants, refineries, grain processing, and other industrial sites with classified hazardous areas.

Performance and Functional Considerations

The built-in photocell provides automatic on/off control based on ambient light, reducing the need for manual switching in hazardous areas. The enclosure is designed to maintain explosion proof integrity while supporting this functionality.

The IP65 rating means the box is protected against dust ingress and water projected from any direction. This supports reliable operation in washdown areas or exposed outdoor locations.

UL 844 Hazardous Locations and UL 1598 Wet Locations listings confirm suitability for use in classified and wet environments. The enclosure is also ABS certified for marine applications.

The junction box supports both 1/2 inch and 3/4 inch NPT conduit entries, allowing flexibility in wiring methods and compatibility with standard industrial fittings.

Installation and Long-Term Use

The box can be mounted on either walls or ceilings, depending on site requirements. The compact 5.6 x 5.6 x 4.2 inch size allows installation in tight spaces or on existing structures.

The enclosure is constructed for long-term durability in harsh environments, including exposure to dust, water, and corrosive atmospheres. The IP65 rating supports use in washdown or outdoor areas.

The built-in photocell is integrated into the enclosure, reducing the need for separate control devices in hazardous locations. This simplifies wiring and minimizes penetrations that could compromise explosion proof integrity.

LED Lighting Supply provides a 5-year warranty on this junction box, supporting long-term reliability in demanding applications.

How This Fixture Is Commonly Used

After installation, the built-in photocell automatically switches connected loads on or off based on ambient light. This reduces manual intervention in hazardous or hard-to-access areas.

The enclosure is typically mounted to a wall or ceiling using standard hardware. Once installed, you can connect conduit through the 1/2 inch or 3/4 inch NPT entries as required by your wiring plan.

In day-to-day operation, the box is designed to remain sealed and maintain its explosion proof rating. The IP65 enclosure prevents dust and water ingress, supporting reliable function in washdown or outdoor environments.

Routine inspection may be performed as part of facility maintenance, but no regular adjustment is required for the photocell or enclosure under normal conditions.
