Can I drive this Relay to control Pool Pump?

I read in another post that someone wanted to use the following relay to switch on and off his 240 V AC 1 HP Pool Pump.

See http://ca.mouser.com/ProductDetail/Omron-Industrial/G7L-2A-BUBJ-CB-AC24/?qs=Pjd0UV7BHP%252bQ6pv360yf1RaaCWB%252b%252bB%252bz

Can I drive this direct from a 5V pin on the Arduino? If not what would the circuit look like to connect to an Arduino UNO?

Thanks for your help.

That relay is controlled with 24 volt AC. You can't directly contol it with an Arduino.

Should have seen that. So I guess I need to ask the more general question:

I need a relay or contactor of some sort to switch on/off my 240V AC 1 HP (746 Watt) pool pump. It seems like the pump is a high in-rush current device that may affect the device choice. Also I would really like to drive this straight from Arduino so it should obviously be isolated electrically from the Arduino board.

Thanks everyone.

Would this do the trick?

Seems like it should!

Best thing to do is use a transistor to power a relay, which in turn powers the pump.

Or use a 5A random turn on SSR, which can be driven direct from the Arduino, such as http://uk.farnell.com/crydom/cx240d5r/ssr-5a-240vac/dp/1613825.
