The contactor is a mandatory safety device that switches of the voltage if there is no power demand from the EV.
The contactor switches 230/400 volt AC mains supply to the EV.
The configuration is a 4 pole for switching N, L1, L2 and L3. The operation is “Normally Open” (NO) which means that activating will close the contacts. The contactor is rated at 20 Amp (AC-1). The coil activation voltage is 12 volt DC which matches the IQLaad Charge Controller Plug & Charge.
This contactor is activated by the Charge Controller. As soon as Charge controller detects EV that requires power, it will provide a 12 Volt signal to the activation coils of the contactor. The contacts will close and power will be available to charge the EV.
