When it may not be suitable

How to use
To use the Aptel ZU-403, first strip approximately 10-11 mm of insulation from the end of each wire. Lift the orange lever on the connector to the open position, insert the stripped conductor fully into the port, and then push the lever back down to lock the wire securely in place. Repeat this process for the remaining ports as needed. Ensure that the wire is fully seated and that no bare copper is exposed outside the connector housing.
What to consider before purchase
Verify the total number of wires required for your specific circuit
Ensure the wire cross-section falls within the 0.08-4 mm2 range
Check the available space in your junction box to ensure the connector fits comfortably
Usage recommendations
Always ensure that the power supply is completely disconnected before performing any electrical work. Test the connection by gently pulling on the wires to confirm they are firmly held by the spring clamp mechanism.
