Do credit cards offer more fraud protection?

Do credit cards offer more fraud protection than debit cards? I have heard credit cards you are only liable for $50 if lost or stolen, but then I read that some debit cards can have just as much protection. Anyone know much about this?
Update: Does Wachovia offer me zero liability for fraud or is there any way I can get this from Wachovia? If not I might switch to another bank that will offer this?
