Surge protectors (MOVs) in extension leads are generally self-resetting devices.
If the extension lead does not work after a surge event it may be that the protection (fuse) for the MOV has become open circuit.
If the device has a replaceable fuse you can try to change that or change the fuse in the plug. If that does not work we recommend that you replace the extension lead
