NORDEL NLT535 Universal Terminal Block 3P+N+PE, 5x2.5–35 mm², Grey, for Aluminum and Copper Conductors

The NORDEL NLT535 is a professional-grade universal terminal block engineered for secure and efficient electrical distribution. Designed with a 3P+N+PE configuration, this unit provides five connection points capable of accommodating conductors with cross-sections ranging from 2.5 to 35 mm². Its robust construction ensures reliable performance in both residential and industrial electrical systems, providing a stable interface for power management.

Advantages

This terminal block stands out due to its versatility in handling both aluminum and copper conductors, making it a flexible solution for various installation requirements. The design prioritizes electrical safety and long-term connectivity, ensuring low contact resistance and high mechanical stability. Its compact grey housing is built to withstand standard environmental conditions, while the clear labeling and accessible connection points facilitate quick and error-free wiring during installation.

Suitable for

• Industrial electrical distribution panels
• Residential power supply systems
• Connecting aluminum and copper power cables
• Main power distribution blocks

This terminal block may not be suitable for applications involving extremely high-vibration environments without additional protective enclosures. It is also not intended for use in high-temperature industrial processes that exceed the rated thermal limits of the housing material.

Key specifications

• Configuration: 3P+N+PE
• Number of connection points: 5
• Conductor capacity: 2.5–35 mm²
• Material compatibility: Aluminum and Copper
• Color: Grey

To use the NORDEL NLT535, ensure the power supply is completely disconnected before starting any work. Strip the insulation from the conductor ends according to the required length, insert the wires into the designated terminals, and tighten the screws to the specified torque to ensure a secure mechanical and electrical connection. Verify that all connections are firm and that no loose strands are protruding from the terminal block before restoring power.

What to consider before purchase

• Verify the total current load of your circuit matches the terminal block ratings
• Ensure the conductor cross-section falls within the 2.5–35 mm² range
• Check if the installation environment requires specific IP-rated enclosures

For optimal performance, it is recommended to periodically inspect the terminal connections for tightness, especially in systems subject to thermal cycling, and always use appropriate tools to prevent damage to the screw heads or conductor strands.
