If the radiator comes into contact with a hazardous live conductor, then other means of protection against electric shock according to IEC 61140 (BS EN 61140) have been breached for some reason.
Depending on that breach, it's not necessary, in all cases, for an installation protective device to operate - for example, if a Class II product is destroyed.
That's the function of additional protection. Discuss.
