Explosion Proof Junction Box | Class 1 Div 1 | Class 1 Div 2 | 3/4 NPT

Product Overview

This explosion proof junction box is designed for use in hazardous locations classified as Class 1 Division 1 and Class 1 Division 2. It features 3/4 NPT knockouts as standard for conduit entry and wiring connections.

The enclosure measures 5.6 by 5.6 by 4.2 inches. Construction supports use in environments requiring robust protection against dust, water, and corrosive elements.

This junction box is suitable for wet locations and marine outside type environments. The design supports installation in a wide range of hazardous and industrial settings.

Durability and environmental resistance are supported by an IP66 rating and a 5-year warranty from LED Lighting Supply.

Where This Product Fits Best

This junction box is intended for hazardous locations where explosive gases, vapors, or dusts may be present. It is suitable for use in areas classified as Class I Division 1 Groups C and D, and Class I Division 2 Groups A, B, C, and D.

It is also approved for Class II Division 1 Groups E, F, and G, Class II Division 2 Groups F and G, and Class III locations. This covers a broad range of industrial, manufacturing, and processing environments.

The enclosure is UL 1598 listed for wet locations and UL 1598A listed for marine outside type use. This allows installation in outdoor, washdown, or marine-exposed areas where water ingress is a concern.

Standard 3/4 NPT knockouts provide compatibility with common conduit and cable systems used in hazardous and industrial facilities.

Performance and Functional Considerations

The IP66 rating means this junction box is protected against dust ingress and high-pressure water jets from any direction. This supports use in environments with heavy washdown, rain, or airborne particulates.

UL 844 Hazardous Locations and ABS listings confirm suitability for use in regulated hazardous and marine environments. The enclosure is designed to contain and isolate electrical connections in classified areas.

Dimensions of 5.6 x 5.6 x 4.2 inches provide adequate space for wiring terminations and splicing while maintaining a compact footprint for tight installations.

Durable construction supports long-term use in demanding environments, with a 5-year warranty provided by LED Lighting Supply.

Installation and Long-Term Use

Standard 3/4 NPT knockouts allow direct connection to rigid conduit systems commonly used in hazardous locations. This supports straightforward integration into existing wiring infrastructure.

The enclosure is suitable for wall, ceiling, or structure mounting as required by site conditions. The compact size allows installation in confined or crowded spaces.

IP66 protection and marine outside type rating support long-term reliability in wet, corrosive, or outdoor environments. The enclosure is designed to prevent water and dust ingress during normal operation.

Routine inspection and maintenance are supported by the accessible enclosure design. The robust construction minimizes the risk of damage from impact or environmental exposure.

How This Fixture Is Commonly Used

After installation, this junction box provides a sealed enclosure for electrical connections in hazardous areas. You can use it to terminate, splice, or branch circuits where explosion proof protection is required.

The 3/4 NPT knockouts allow you to route conduit or cable as needed for your application. The enclosure supports routine inspection and access for maintenance without compromising the hazardous location rating.

In wet or marine environments, the IP66 and UL 1598A ratings allow you to rely on the enclosure to keep internal wiring dry and protected from corrosion. The box can be mounted in exposed locations without additional weatherproofing.

Day-to-day, the enclosure remains sealed and requires minimal interaction unless you are performing wiring changes or inspections. The robust design supports long service intervals and consistent protection.
