The Distribution Junction Box is an advanced electrical terminal block designed to provide secure and efficient power distribution, particularly for copper and aluminum conductors. It enables a clean, organized setup in power management systems, simplifying installation, expansion, and maintenance.

The JHT5 Series is available in multiple configurations such as single-pole and dual-pole variations, allowing it to fit a wide range of wire sizes from Cu: 2.5–240mm² and Al: 6–240mm². These boxes are suitable for voltages up to 800V and can carry high current loads up to 160A (copper) or 145A (aluminum), making them ideal for industrial and commercial use.

Key Features and Advantages

• High Current and Voltage Tolerance

The JHT5 Distribution Junction Box supports high-capacity current flows, making it suitable for demanding applications such as main distribution lines, switchboards, and control cabinets.

• Durable and Heat-Resistant Housing

The housing is made of high-grade polyamide (PA), known for excellent thermal stability. It can withstand temperatures ranging from -40°C to +85°C without compromising performance.

• Secure Mounting Options

These boxes support DIN rail and screw mounting, providing flexibility during setup. A 5mm hexagon screw mechanism ensures stable and secure conductor termination.

• Corrosion and Oxidation Resistance

With nickel-plated brass guide bars inside, the terminal ensures outstanding electrical conductivity and excellent resistance to oxidation and corrosion, even in harsh industrial environments.

• Easy to Identify Color Coding

Available in color-coded options like Yellow-Green, Blue-Grey, and Grey, the JHT5 Series makes circuit identification fast and error-free, improving installation safety.

• Multiple Models, Multiple Applications

The product codes (JHT5-50-PE, JHT5-50-GY, JHT5-50-BE, etc.) allow users to select the right configuration based on wiring requirements. Both single and double conductor hole types are offered to accommodate different wiring layouts.

Applications of Distribution Junction Box

• Industrial Control Panels: Ideal for use in power control systems where space-saving and reliable wiring are required.
• Building Electrical Systems: Used in distribution cabinets for lighting, HVAC, and elevator control.
• Renewable Energy Installations: Suitable for solar, wind, and battery energy storage systems where high-voltage and current rating is necessary.
• Machine Manufacturing: Simplifies the internal wiring of machinery, enhancing safety and reducing setup time.
• Marine and Railway Systems: With its corrosion-resistant internal structure, it is suitable for humid or mobile environments.

How to Use a Distribution Junction Box

• Strip the conductor wire to the appropriate length depending on the wire gauge.
• Insert the stripped wire into the wiring hole aligned with the brass guide bar.
• Tighten the hexagonal screw with a 5mm tool to secure the conductor firmly in place.
• Mount the box onto a DIN rail or use screws to fix it inside the enclosure.
• Ensure color coding and labeling for safety and easy maintenance.

No special tools or accessories are required beyond standard hand tools, and the compact design allows for space-saving in tight enclosures.
