HiSmart NV821761 eenpolige verdeelkast 80A

HiSmart NV821761 unipolar junction box rated 80 A is designed to house and protect a single-pole electrical connection in distribution systems. The compact enclosure mounts on a DIN rail and features a transparent cover for visual inspection of the connection. The body is made of flame-retardant PA (nylon), and the brass-plated terminals provide durable, corrosion-resistant conductive contacts suitable for residential and light commercial wiring, including solar PV junctions.

Advantages

The junction box supports up to 80 A and accommodates multiple cable configurations with secure brass-plated terminals that resist corrosion and ensure good conductivity. The transparent cover enables quick visual checks without disassembly. The PA nylon housing meets V0 UL94 flame-retardant classification and withstands elevated temperatures. DIN-rail mounting simplifies installation in electrical panels.

Suitable for

• Single-pole cable connections in distribution panels
• Solar PV string junctions and related DC/AC wiring
• Residential and light commercial electrical installations
• Organizing and protecting cable branches on a DIN rail

How to use

Mount the junction box on a compatible DIN rail inside an electrical panel. Route the cables to the appropriate terminal entries and strip conductor insulation according to the cable cross-section specifications. Insert conductors fully into the terminals and tighten the terminal screws to the manufacturer-recommended torque. Close the transparent cover to protect the connection and allow visual inspection.

Recommendations

Use the junction box within the specified current and voltage ratings and select cable cross-sections that match the listed ranges. Perform installation and maintenance following applicable electrical codes and safety practices; disconnect supply before working on the circuit. For outdoor or harsh environments, provide additional enclosure protection as this product is intended for panel or DIN-rail installations.
