Aluminum Junction Box Material Specifications
Shell material: Made of brand new nylon PA66, capable of withstanding hightemperatures and pressures and maintaining excellent performance invarious harsh environments.
Conductive Material: Internal conductive components use copper- or tin-plated metals, prioritizing excellent conductivity, stable contact, andcorrosion resistance.
Surface Treatment: Common processes include tin plating, nickel plating,and silver plating, which enhance oxidation resistance and long-termreliability.
Color Differentiation: Different colors serve not only for appearance but alsofor specification identification and circuit management, facilitating assemblyand maintenance.
Internal structure and wiring range
Thickened aluminum nickel-plated conductor.
Aluminum conductors are lightweight, have a large cross-section,and exhibit good corrosion resistance.
Compatible with copper/aluminum wires.
16~240mm2
Wiring range 63~380A current carrying capacity.
Reasons for the secure wiring of aluminumterminals
Secure and non-loose wiring
Hex socket screws + toothed wire clamping frame
High-strength hex socket screws ensure a secure connectionwithout stripping.
Combined with a toothed wire clamping frame,the wires remain firmly in place and do not slip
What is the wiring method for SAL5 aluminumterminals?
Wiring is quick and easy.
Unscrew the hex socket screw before wiring.
Tighten the screw after connecting the wire. Wiring is now secureand durable.

How to Maintain Terminal Blocks
Regular Inspection
- Regularly inspect terminal blocks for signs of wear, corrosion, or loose connections.
Clean Terminal Blocks Regularly
- Use a soft brush and compressed air to clean terminal blocks and remove any dirt, dust, or debris that may accumulate on the contact points.
If Any Loose Connection Is Found
- If any connection becomes loose, use a screwdriver to tighten the screws to the manufacturer’s recommended torque value. This helps ensure a safe and reliable electrical connection.
Check for Overheating
- Inspect terminal blocks for signs of overheating, such as discoloration or deformation. Overheating may be caused by excessive current or poor contact resistance, and should be addressed promptly to prevent further damage.
Always Use Properly Sized Terminal Blocks
- Be sure to select the correct size and type of terminal block according to the application requirements. Using undersized terminal blocks may lead to overheating, poor contact, and other issues.
Troubleshoot Faulty Connections
- If a faulty connection occurs, check the wiring for short circuits, open circuits, or incorrect positioning. Use a multimeter or other diagnostic tools to identify the root cause of the problem.
Follow the Manufacturer’s Guidelines
- Always follow the terminal block manufacturer’s instructions for installation, operation, and maintenance to ensure safe and reliable performance.
