Description
The KEDU KOA12/400V is an electromagnetic motor switch with a built-in no-voltage release, motor protection, motor brake, emergency stop, and phase inverter. It is used on selected Güde 400 V firewood saws.
Practical Information
The KEDU KOA12 is equipped with a no-voltage release and motor brake. On many installations, the blue wire must be connected to N (neutral). Without a neutral connection, the switch may not latch, or the motor brake may not operate correctly.
Wiring may vary between different machines and installations. If you are unsure, the installation should be carried out by a qualified electrician.

Important
This switch is available in both 230 V and 400 V versions. Always verify the voltage of the original switch before ordering.
Always wire the switch according to the terminal numbering and the wiring diagram – never rely solely on wire colours. Wire colours and cable positions may vary between different versions of the same switch.
