How should it be connected?
Connect it in parallel across the line or supply you want to protect. A fuse in series is commonly added as a backup for protection against a failed varistor.
Is 240 V nominal the same as its maximum operating voltage?
No. The nominal voltage is the varistor's reference voltage, not its continuous operating limit. Check the maximum continuous AC and DC ratings in the datasheet for your circuit before use, and choose a part rated above the circuit's normal voltage.
