Suitable for

• Industrial control cabinet wiring
• Automation and process control systems
• Power distribution panels
• Modular electrical installations

When it may not be suitable

This terminal block is not intended for use in high-power applications exceeding its 32A current rating or 630V voltage limit. It is also not suitable for environments requiring specialized explosion-proof certifications or extreme chemical resistance beyond standard industrial specifications.

Key specifications

• Conductor cross-section: 4mm²
• Rated current: 32A
• Rated voltage: 630V
• Number of connections: 4
• Mounting type: DIN rail
• Color: Dark gray

How to use

To install the terminal block, snap it securely onto a standard DIN rail. Insert the stripped wire ends into the designated conductor entry points until they are firmly seated. Ensure that the connection is tightened according to the manufacturer's torque specifications to maintain optimal electrical conductivity and mechanical integrity. For multi-conductor configurations, ensure that all wires are properly organized to prevent strain on the terminal points.

What to consider before purchase

• Verify that the 4mm² wire size is compatible with your specific application requirements.
• Ensure the DIN rail type in your cabinet is compatible with the mounting mechanism.
• Confirm that the total current load of your circuit does not exceed the 32A limit.
• Check the available space in your enclosure to accommodate the physical dimensions of the terminal block.

Usage recommendations: Always use appropriate wire stripping tools to avoid damaging the conductor strands. Regularly inspect terminal connections during routine maintenance to ensure they remain tight and free from oxidation.
