Required solution for Relay burning issue
Hi All,
We have a product to control 3phase agriculture motor.
We have deployed many units in the field and during rainy seasons our product is getting damaged.
I have shown device connection diagram in attached image.
Damage is happening to Relay and all the semiconductor components on the board.
Relay contact tracks on the board is melting out and all the GND and VCC tracks on the board are damaging.
Images of the damaged boards are attached for reference.
You can find the data sheet of the relay in below link

I suspect during thunder or lightning condition, very high voltage is striking the relay contacts.
Isolation between relay contact and coil is breaking down and this heavy voltage is passed to board through relay coil.
Please provide suggestions to solve this issue and protect relay from high voltage surges.
