One of the most important bits of information given by the OP in this thread was that the device was "Class 2," This tells that the mains device ( tranformer in this case ) is energy limiting and will open circuit if overloaded, temperature or current.
As noted in the post above, there is a fusing device, most often on the primary of the transformer, sometimes it can be bypassed, other times not. Be aware that bypassing it will remove a safety feature of the design, possibly resulting in a dangerous situation.
