How to use
To install the busbar, first ensure that the power supply to the terminal block assembly is completely disconnected. Align the comb teeth with the designated jumper slots on the terminal blocks. Press the busbar firmly into the slots until it is fully seated and locked into position. Once installed, verify that all connections are tight and that the busbar is properly aligned across all ten poles before restoring power to the system.
What to consider before purchase
Verify the cross-section compatibility of your existing terminal blocks.
Check the physical spacing and pitch of your terminal block series.
Ensure the 10-pole length fits within your specific enclosure layout.
Usage recommendations
Always ensure that the busbar is fully inserted into the terminal slots to prevent loose connections or arcing. Regularly inspect the installation during routine maintenance to confirm that the busbar remains securely seated.
