Waterproof Plastic Junction Box IP65-IP68 | Bsumwell Electrical Enclosures (ABS+PC, Customizable)

High-Quality Waterproof Plastic Junction Box & Electrical Enclosures

Bsumwell Plastic Junction Box Series: IP65–IP68 Certified for Outdoor & Industrial Electrical Protection

Bsumwell’s waterproof plastic junction box series—including PS-KT, PS-RA, PS-RT, PS-WT, PS-KG, PS-NT, and PS-GT—specializes in durable, corrosion-resistant electrical enclosures for harsh outdoor and industrial environments. Crafted from high-toughness ABS or ABS+PC engineering plastics, our enclosures deliver exceptional impact resistance and stable performance in temperatures ranging from -20℃ to +80℃.

All models are CE, ROHS certified and fully compliant with IEC60439 standards, boasting IP65 to IP68 ingress protection (PS-GT/PS-NT series support short-term submersion up to 1m). This makes them 100% impervious to outdoor rain, heavy dust, chemical corrosion, and extreme temperature fluctuations—ideal for uncompromising electrical protection.

Trailer & marine electrical systems
Underground landscape cables & buried power installations

PS-KG / PS-KT Series | Medium-Sized Universal Enclosures

Featuring snap-on or hinge closures for quick, tool-free access, these models balance robust IP65 protection with cost-effectiveness—perfect for bulk orders.

Core Applications:

Commercial outdoor lighting systems
Small industrial equipment wiring
General-purpose electrical junction protection

PS-RA / PS-RT Series | Specialized Environment Enclosures

Enhanced silicone sealing and upgraded material formulations resist extreme heat (up to +85℃) and heavy dust, tailored for high-stress industrial settings.

Core Applications:

High-temperature manufacturing workshops
Mining & construction site electrical systems
Desert or coastal high-corrosion environments
