NORDEL NLT350 Universal Terminal Block 3x2.5-50 mm², Yellow/Green, for Aluminum and Copper Conductors

The NORDEL NLT350 is a high-performance universal terminal block engineered for secure and reliable electrical connections in diverse environments. Designed to accommodate three conductors with cross-sections ranging from 2.5 to 50 mm², this component provides a versatile solution for managing electrical distribution. Its robust construction supports both aluminum and copper conductors, making it a dependable choice for grounding applications where safety and consistent conductivity are paramount.

Advantages

The primary benefit of the NORDEL NLT350 lies in its universal compatibility with different conductor materials, allowing for seamless integration of aluminum and copper wiring within the same system. The terminal block is built to withstand demanding conditions, ensuring long-term mechanical stability and low contact resistance. Its distinct yellow and green color coding facilitates quick identification for grounding purposes, which helps in maintaining organized and safe electrical panels. The compact design optimizes space within distribution boxes while maintaining high electrical performance standards.

Suitable for

• Grounding systems in residential and industrial electrical installations
• Connecting aluminum and copper conductors in distribution boards
• Electrical projects requiring reliable multi-port wire termination
• Applications where space-saving and secure connectivity are required

When it may not be suitable

This terminal block is not intended for use with conductors outside the specified 2.5 to 50 mm² range, as this may compromise the integrity of the connection. It is also not suitable for high-vibration environments unless additional strain relief measures are implemented according to local electrical codes.

Key specifications

• Number of ports: 3
• Conductor cross-section range: 2.5 to 50 mm²
• Material compatibility: Aluminum and Copper
• Color: Yellow/Green
• Application: Grounding and distribution

How to use

To use the NORDEL NLT350, ensure the power supply is disconnected before starting any installation. Strip the insulation from the conductor ends according to the required length to ensure full contact within the terminal port. Insert the wire into the designated port and tighten the screw mechanism firmly to secure the conductor. Verify that the wire is held tightly and cannot be pulled out. Ensure that all connections are made in accordance with local electrical safety regulations and standards.

What to consider before purchase

• Verify that the conductor size falls within the 2.5 to 50 mm² range
• Ensure compatibility with your specific wiring material (aluminum or copper)
• Check the available space in your distribution enclosure
• Confirm that the terminal meets the grounding requirements of your project

Usage recommendations

Always use a calibrated torque screwdriver to tighten the terminal screws to the manufacturer's recommended torque settings to prevent damage to the conductors or the terminal block itself.
