Product Overview
This is an explosion proof junction box designed for use in hazardous locations. It is built with a 3/4 NPT threading and measures 5.6 x 5.6 x 4.2 inches. The enclosure is engineered for environments where flammable gases, vapors, or dusts are present.
The junction box is UL listed for Class I Division 1 and Division 2, as well as Class II and Class III hazardous locations. It carries an IP66 rating for weatherproof protection and is suitable for use in wet locations and marine outside type environments.
Operating temperature range is -76°F to 140°F. The box is constructed for durability in petrochemical, industrial, and marine settings.
Where This Product Fits Best
This junction box is intended for installation in areas where explosion proof protection is required by code or site safety policy. Typical locations include refineries, chemical plants, fuel storage facilities, and industrial processing areas with hazardous atmospheres.
It is also suitable for marine environments and outdoor installations exposed to weather, salt spray, or washdown. The 3/4 NPT threading supports integration with standard conduit and cable systems used in hazardous locations.
Performance and Functional Considerations
The enclosure is rated for Class I Division 1 Groups C and D, and Class I Division 2 Groups A, B, C, D. It is also approved for Class II Division 1 Groups E, F, G, and Class II Division 2 Groups F, G, as well as Class III locations.
IP66 protection allows the box to withstand high-pressure water jets and prevent dust ingress. The operating temperature range supports use in both extreme cold and high-heat environments.
UL 1598 and UL 1598A listings confirm suitability for wet locations and marine outside type applications. The ABS certification supports use in marine and offshore installations.
Installation and Long-Term Use
The box is designed for surface mounting and connection to 3/4 NPT conduit. Its compact size allows for installation in tight spaces or on equipment skids.
Durable construction supports long-term use in corrosive or high-vibration environments. The IP66 rating ensures the enclosure remains sealed against water and dust over time.
