Designed and manufactured by SEEKINGLED, the BHD51 Series explosion-proof junction box adopts the flameproof (Ex d) principle in accordance with IEC 60079-1. It is engineered for safe electrical connections in high-risk hazardous areas such as oil & gas, petrochemical, and chemical industries.

It is currently the only product on the market that enables fast, tool-free cable connection while effectively preventing misoperation. The junction box provides secure and reliable performance in the following hazardous zones:

• Gas atmospheres: Zone 1 and Zone 2
• Dust atmospheres: Zone 21 and Zone 22

The BHD51 Series supports both surface mounting and pendant (suspended) installation. It offers flexible wiring configurations, including 1-in-1-out, 1-in-2-out, 1-in-3-out, 2-in-2-out, and other combinations, with compatibility for both M20 and M25 cable gland thread sizes.

The product has been certified to international ATEX and IECEx standards, ensuring full compliance with global explosion-proof requirements.

This design makes on-site wiring faster and safer, significantly reducing installation time and the risk of human error. It is particularly well-suited for complex lighting and power distribution systems in hazardous areas.
