Protective terminal ZO-2107, blue A14-2136

Protective terminals – safety and reliability of installation

The ZO-2107 protective terminal is an element used to safely connect protective conductors (PE) in electrical installations. Its main task is to provide effective protection against electric shock by diverting fault current to ground. Made of copper, it offers good conductivity and connection durability. Designed for mounting on TS35 rail, which simplifies and speeds up installation.

Construction and application

The ZO-2107 terminal is designed for connecting protective conductors with a nominal cross-section of 4 to 6 mm². Its screw connection-based construction guarantees a secure and stable connection, minimizing the risk of loosening over time. The lack of insulation on the terminal requires special caution during installation to avoid accidental contact with live conductors. This is particularly important when working on existing installations, where the power must be switched off before starting work.

This terminal finds application in:

• Electrical distribution boards – as a connection point for protective conductors to the PE busbar.
• Distribution boards – providing safe grounding of circuits.
• Control cabinets – protecting devices from damage caused by overvoltage.
• Building installations – in houses, apartments, offices and other public utility facilities.

Key features and benefits

• Wire cross-section 4-6 mm²: Allows adaptation to a wide range of applications and cables of different thicknesses.
• Copper material: Ensures high electrical conductivity and corrosion resistance, which translates into long-lasting and reliable operation.
• Screw connection: Guarantees a secure and stable connection, minimizing the risk of loosening over time. This is particularly important in installations exposed to vibrations or temperature changes.
• Mounting on TS35 rail: Enables quick and easy mounting in standard electrical distribution boards, saving time and installation costs.
• No surface coating: Allows direct contact with the grounding busbar, ensuring optimal protection efficiency.
• Blue color: Facilitates identification of the terminal as a protective element, in accordance with applicable standards and safety regulations.
