Rated current: 32A
Rated voltage: 800V
Connection type: 2-conductor
Mounting type: DIN rail
Color: Dark gray
How to use
To install the terminal block, snap it onto a standard DIN rail until it clicks securely into place. Strip the insulation from your conductors to the appropriate length and insert them into the terminal points. Tighten the screws to the recommended torque to ensure a firm mechanical and electrical connection. Ensure that all wiring complies with local electrical codes and that the total load does not exceed the rated capacity of the terminal block.
What to consider before purchase
Verify that the 4mm² cross-section is compatible with your wire gauge requirements.
Ensure the DIN rail type in your enclosure matches the mounting requirements of the terminal block.
Check that the 32A and 800V ratings are sufficient for your specific circuit load.
Confirm the total number of terminal blocks needed for your wiring layout.
Usage recommendations
Always ensure that power is disconnected before performing any wiring or maintenance on the terminal block. Use appropriate tools for tightening connections to prevent damage to the screw terminals and ensure optimal contact pressure.
