JHUKK-500 500A High Current Unipolar Junction Box for Heavy-Duty Power Distribution

TheJHUKK-500 is a high-current unipolar junction box designed for heavy-duty electrical connections, power distribution and industrial wiring applications. With a rated current of 500A and a rated voltage of 690V IEC, it is designed for electrical systems where high-current cable connection and distribution are required.

As the high-current model in the JHUKK series, the JHUKK-500 focuses on applications that require a higher current rating and a robust connection structure. It provides multiple connection positions for different conductor sizes, allowing main and branch conductors to be organized within one compact terminal block.

500A High-Current Connection

The most distinctive feature of the JHUKK-500 is its 500A rated current.

Compared with lower-current models in the JHUKK series, the JHUKK-500 is positioned for applications where higher electrical current capacity is required. It can be used as a connection point for power distribution systems, electrical cabinets, industrial machinery and other high-current installations.

The product is designed to connect a main conductor with several branch conductors, helping create a more organized electrical distribution layout.

Multiple Connection Options

The JHUKK-500 provides several conductor connection positions to accommodate different wiring requirements.

The specification shown for the model includes:

• 4×15.5×0.8 to 8×24
• 6–35 mm² ×2
• 2.5–16 mm² ×5
• 2.5–10 mm² ×4

This multi-position configuration allows different types and sizes of conductors to be connected through one junction box.

For electrical installers and equipment manufacturers, having multiple connection positions in one component can make power distribution wiring more convenient and organized.

Designed for Heavy-Duty Electrical Applications

With a rated current of 500A, the JHUKK-500 is suitable for heavy-duty electrical applications where high-current connections are required.

Typical applications include:

• Industrial power distribution
• Electrical distribution cabinets
• Control and electrical cabinets
• Industrial machinery
• Large electrical equipment
• Power supply systems
• Motor and equipment connections
• Main cable distribution
• Branch circuit connections
• High-current electrical installations

The product can be used where several electrical circuits need to be connected and arranged within a compact distribution structure.

PA Nylon Housing

The JHUKK-500 uses a PA Nylon housing for its main body.

The material has a UL94V0 flame retardant grade, making the housing suitable for electrical connection components where flame-retardant material performance is required.

The housing provides a compact structure around the internal connection components while helping organize the cable connection positions.

Brass Nickel-Plated Metal Components

The metal components are made from brass with nickel plating.

The brass construction provides a conductive connection path, while the nickel-plated surface helps improve the surface characteristics of the metal components.

This combination is suitable for electrical connection applications requiring stable contact between conductors and the terminal components.

Transparent Cover for Visual Inspection

The JHUKK-500 features a transparent cover.

The transparent design allows users to visually check the internal connection area. This can be useful during installation, inspection and maintenance.

For electrical cabinets and distribution equipment, being able to observe the connection area can make routine checking more convenient.

Compact 47 × 95 × 50 mm Structure

Despite its 500A current rating, the JHUKK-500 has compact overall dimensions of:

47 × 95 × 50 mm (L × W × H)

Its compact structure helps save installation space inside electrical cabinets and distribution equipment.

The connection points are integrated into one housing, allowing the terminal to provide a centralized connection solution without requiring several separate terminal components for different branch connections.

Practical Power Distribution Solution

The JHUKK-500 is designed to provide a practical connection point for power distribution systems.

In many electrical installations, a main power cable needs to be connected to multiple branch cables. Using a dedicated high-current junction box can help organize these connections and make the overall wiring layout more structured.

The JHUKK-500 combines multiple conductor connection positions with a 500A rated current in one compact housing, making it suitable for high-current distribution applications.

Industrial Applications

The JHUKK-500 can be used in a wide range of electrical and industrial environments.
