Product information

Description

The CNC NV821761 unipolar junction box is rated for 80A and designed for safe, reliable electrical power distribution and wire connection in residential, commercial, and industrial electrical installations. This essential component ensures secure cable management, organized circuit termination, and optimal electrical conductivity for various wiring setups, featuring a transparent cover for easy connection inspection and durable flame-retardant polyamide construction.

Advantages

The unipolar junction box provides a secure and organized method for cable connections and branching within electrical distribution systems. Its flame-retardant PA nylon body offers strong insulating properties and resistance to high temperatures, ensuring reliable performance in demanding environments. The brass-plated terminals deliver excellent electrical conductivity alongside high durability and corrosion resistance. Additionally, the integrated transparent cover allows users to visually inspect the reliability of the cable connections without needing to dismantle the unit.

Suitable for

  • Electrical distribution systems in residential buildings
  • Commercial and industrial electrical installations
  • Electrical panels requiring DIN rail mounting
  • Cable branching and connection setups

When it may not be suitable

This unipolar junction box is not designed for multi-pole applications requiring integrated neutral and earth linking within a single enclosed block unless configured properly for unipolar use. It is also unsuitable for cable cross-sections that exceed the specified maximum clamping capacities of 16 mm².

Key specifications

  • Nominal current: 80 A
  • Voltage rating: AC/DC 690-1000 V AIEC
  • Cable cross-sectional area: 1x (6-16 mm²), 4x (2.5-6 mm²), 2x (2.5-16 mm²)
  • Mounting type: DIN rail
  • Terminal material: Brass plated
  • Body material: PA nylon
  • Safety class: V0 UL94 flame retardant
  • Dimensions: 31 x 70 x 45.5 mm

How to use

Begin by ensuring that the main power supply to the electrical panel is completely switched off to prevent electrical shock. Mount the junction box securely onto a standard DIN rail inside the enclosure. Strip the appropriate length of insulation from the cables according to the required cross-sectional dimensions and insert them into the brass-plated terminals. Tighten the terminal screws firmly to ensure a secure mechanical hold and optimal electrical contact. Finally, close the transparent cover to protect the connections and allow for future visual inspections.

What to consider before purchase

  • Verify that the 80A nominal current rating matches your electrical load requirements
  • Check that your cable cross-sectional areas fall within the supported ranges of 2.5 mm² to 16 mm²
  • Ensure you have sufficient DIN rail space inside your electrical panel for the 31 x 70 x 45.5 mm dimensions

Usage recommendations

Always adhere to local electrical codes and standards during installation, and ensure that all terminal screws are torqued correctly to prevent loose connections and potential overheating.
