The design facilitates efficient cable management, reducing clutter within enclosures while maintaining high electrical integrity. With a high current capacity and compatibility with various wire gauges, it provides a flexible solution for demanding power distribution tasks. The IP2x protection rating ensures a basic level of safety against accidental contact, contributing to a secure working environment during and after installation.

Suitable for

• Earth connection distribution in electrical panels
• Professional electrical installations in residential and commercial buildings
• Organizing conductors in distribution boards
• Systems requiring compliance with IEC 60998-2-1 standards

When it may not be suitable

This terminal block is not intended for use in environments where high levels of moisture, dust, or corrosive substances are present, as it does not provide a high degree of ingress protection. It is also not suitable for applications exceeding the specified voltage or current limits, as this could lead to overheating or component failure.

Key specifications

• Maximum current: 100 A (with 25 mm² input) or 80 A (with 16 mm² input)
• Voltage rating: 400 V~
• Connection capacity: 4 x 1.5 to 16 mm²
• Length: 47 mm
• Color: Green (Earth)
• Protection rating: IP2x
• Standard compliance: IEC 60998-2-1

How to use

The terminal block is supplied ready for use with screws in an untightened state to facilitate quick installation. Begin by mounting the block onto a compatible rail using the universal support or directly onto a 12 x 2 mm flat bar. Once securely positioned, insert the stripped conductors into the designated holes. Ensure that the wires are fully seated before tightening the screws to the appropriate torque to establish a firm electrical connection. Verify that all connections are secure and that the wiring configuration matches your circuit diagram.

What to consider before purchase

• Verify that the current and voltage requirements of your system do not exceed the specified limits.
• Ensure you have the correct mounting hardware, such as the universal support rail, if not already present in your panel.
• Check that the wire cross-sections fall within the supported range of 1.5 to 16 mm².

Usage recommendations

Always ensure the power supply is completely disconnected before performing any installation or maintenance work on the terminal block. Use appropriate tools to tighten the screws to prevent damage to the terminal threads or the conductors.
