FAQs
What is CAGE CLAMP® technology?
CAGE CLAMP® is a spring-loaded clamping technology that allows for quick and secure screwless connections of solid and stranded conductors.
What wire sizes can the WAGO 2007-8821 accommodate?
The terminal block can accept wire sizes from 0.5mm² to 10mm² (20 AWG to 8 AWG).
What is the rated voltage of the terminal block?
The terminal block has a nominal voltage rating of 500V.
What type of rail does the terminal block mount on?
It mounts on a DIN 35 rail.
Are there any special tools required for installation?
No special tools are needed. Wires can be directly inserted into the CAGE CLAMP® mechanism.
What is the operating temperature range?
The operating temperature is 105°C.
What are the dimensions of the terminal block?
The dimensions are 8mm width, 65.3mm height, and 99.6mm length.
Where can the terminal block be used?
The terminal block can be used in control cabinets, industrial automation, and current transformer circuits.
Troubleshooting
Device malfunction
Check the connections in the terminal block to make sure wires are properly inserted and secured. Also check that the correct wire gauge is used
Poor conductivity
Ensure wires are fully inserted and that the CAGE CLAMP® mechanism is properly engaged. Check for corrosion on the wire ends and clean or replace if necessary.
Overheating
Verify that the wire gauge is appropriate for the current load. Check for loose connections, which can cause increased resistance and heat. If necessary, reduce the current load or replace the terminal block with a higher-rated one.
