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.
