Junction Box Hensel 130x130x77 mm, 5x4 mm² CU, IP66, grey

Hensel junction box 130×130×77 mm provides a durable enclosure for electrical branching and secure copper conductor connections. Designed for installations that require protection against dust and powerful water jets, the grey housing accommodates up to five conductors of 4 mm² (CU). The product is suitable for both indoor and outdoor use where a compact, weather-resistant box is needed to organize and protect wiring and terminal connections.

Advantages

The junction box features an IP66 rating that ensures dust-tight performance and resistance to strong water jets, making it appropriate for exposed or damp environments. Its compact dimensions (130×130×77 mm) and internal space designed for five 4 mm² copper conductors allow tidy routing and secure mounting of conductors and terminals. The grey, robust enclosure is built for mechanical stability and long-term outdoor or indoor service.

Suitable for

• Electrical branching and splicing of copper conductors in building installations
• Outdoor junction points exposed to rain or high-pressure cleaning
• Industrial or commercial applications requiring compact weatherproof enclosures
• Small distribution points for lighting circuits, sensors, or control wiring

Key specifications

• External dimensions: 130 × 130 × 77 mm
• Conductor capacity: up to 5 conductors of 4 mm² (copper)
• Ingress protection: IP66 (dust-tight; protected against powerful water jets)
• Color: grey
• Material characteristics: mechanically robust enclosure suitable for indoor and outdoor use

How to use

Mount the box on a suitable flat surface using appropriate screws or brackets, ensuring correct orientation and secure fixation. Open the cover to access the internal wiring area, route copper conductors through prepared cable entries or gland points, and make connections using compatible terminals or splices rated for 4 mm² conductors. After wiring, verify tightness of cable glands and seals, then close and fasten the cover to restore the IP66 protection. Ensure all fittings and termination methods comply with local electrical regulations and safety standards.

Usage recommendations

For reliable weatherproofing, use compatible cable glands or sealed conduit entries and apply proper torque on cover screws. Regularly inspect external seals and mounting points in outdoor installations, and follow local wiring rules when connecting 4 mm² copper conductors.
