Latching RCD

Hi,
I've got an RCD plug from Screwfix (http://www.screwfix.com/prods / 44855/Electrical-Supplies/RCDs/Masterplug-RCD-Plug) that I'm using to provide power to my fish tank. However I want one that latches so that if the power fails when I'm not there the plug will restore power to the fish tank equipment when it returns (so the fish don't freeze to death if there's a power blip when I'm on holiday). Seems like a reasonable requirement but for the life of me I can't find anyone who sells a latching RCD device :/
Can anyone else find one?
Thanks,
Peter.

I've got RCD sockets in my work shop that do not trip when power fails. I expect your RCD plugs work differently.
Make up an extension lead with a RCD socket instead.
