The CAGE CLAMP technology simplifies the installation process, eliminating the need for specialized tools while maintaining a consistent, high-quality contact force. Its robust design ensures long-term performance in demanding industrial environments, making it a dependable choice for professional electrical engineering projects requiring high connection density.

Suitable for

• Motor control applications
• Industrial control cabinet wiring
• High-density electrical distribution systems
• Through-terminal connection setups

When it may not be suitable

This terminal block is not intended for use with conductors outside the specified cross-section range of 0.08 mm² to 4 mm². It is also not suitable for applications requiring direct mounting on surfaces other than standard DIN rails or environments where the required strip length of 8 to 9 mm cannot be maintained.

Key specifications

• Connection type: CAGE CLAMP
• Number of levels: 4
• Width: 6 mm
• Height: 100 mm
• Conductor cross-section: 0.08 mm² to 4 mm²
• Strip length: 8 mm to 9 mm
• Quantity per pack: 50 units

How to use

To use the Wago 281-532, mount the terminal block onto a standard DIN rail within your control cabinet. Prepare your conductors by stripping the insulation to a length of 8 to 9 mm. Open the CAGE CLAMP mechanism using a suitable operating tool, insert the conductor fully into the terminal, and release the clamp to secure the connection. Ensure that each of the four levels is wired according to your circuit diagram to maintain proper electrical distribution.

What to consider before purchase

• Verify that your conductor cross-section falls within the 0.08 mm² to 4 mm² range.
• Ensure you have sufficient space on your DIN rail for the 6 mm width per block.
• Confirm that your installation environment is compatible with the 100 mm height of the unit.
• Check that you have the appropriate operating tools for the CAGE CLAMP mechanism.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring operations. Regularly inspect connections in high-vibration environments to maintain optimal contact integrity over the lifespan of the installation.
