Simet ZSG 1-2.5N Combined Threaded Clamp for Terminal Blocks

The Simet ZSG 1-2.5N is a high-quality combined threaded clamp engineered for secure and reliable electrical connections within terminal blocks. This component is specifically designed to provide excellent mechanical stability and consistent electrical contact for conductors with cross-sections ranging from 1 to 2.5 mm². It serves as an essential element for professional electrical installations, ensuring that wiring remains organized and firmly connected in demanding environments such as control cabinets and industrial distribution boards.

Advantages

The primary benefit of the Simet ZSG 1-2.5N is its robust construction, which guarantees long-term durability and resistance to mechanical stress. By utilizing a threaded clamping mechanism, it ensures a high-pressure connection that minimizes resistance and prevents accidental disconnection. Its compact design allows for efficient space utilization in crowded terminal blocks, making it an ideal choice for complex electrical systems where reliability is paramount.

Suitable for

• Professional electrical installations in control cabinets
• Distribution board wiring and organization
• Industrial automation systems
• Connecting conductors with cross-sections between 1 and 2.5 mm²

When it may not be suitable

This clamp is not intended for use with conductors outside the specified 1 to 2.5 mm² range, as smaller or larger wires may not achieve the necessary contact pressure or mechanical security. It is also not designed for high-vibration environments where specialized locking terminals might be required, nor is it suitable for direct outdoor exposure without appropriate protective enclosures.

Key specifications

• Conductor capacity: 1 to 2.5 mm²
• Connection type: Threaded clamp
• Application: Terminal block integration
• Material: High-strength conductive metal alloy

How to use

To use the Simet ZSG 1-2.5N, first ensure that the power supply to the circuit is completely disconnected to prevent electrical hazards. Strip the insulation from the end of the conductor to the appropriate length, ensuring the copper strands are clean and undamaged. Insert the conductor into the terminal block slot and position the threaded clamp over the wire. Use a compatible screwdriver to tighten the screw until the conductor is firmly secured, ensuring that the connection is mechanically stable and provides optimal electrical conductivity.

What to consider before purchase

• Verify that your conductor cross-section falls strictly within the 1 to 2.5 mm² range
• Ensure compatibility with your existing terminal block rail system
• Check the required torque specifications for your specific installation environment

Usage recommendations

Always perform a pull test after tightening the screw to confirm that the conductor is securely held in place. Regularly inspect connections in high-load systems to ensure that thermal expansion or vibration has not loosened the threaded clamp over time.
