Defective toroidal?

[JMValios]

I purchased this toroidal:
http://www.nuvotem.com/en/products/pdf/0800P1_0209.pdf
When I connect the primary,220V in my country, (brown and blue cables of the transformer) kill the fuses,and the automatic overcharge protection of home,too.Measuring resistance of the primary is only 1,3 ohm.
What's wrong?

Thanks,

1.3 ohms is about right, in fact thats what the spec shows. The primary current cannot be calculated using the DC resistance of the primary as Inductive Reactance is the main ingredient.
If you have the secondaries connected in parallel make sure the black and orange are connected together and the red and yellow together, try it with all secondaries open.
How Do you have it mounted you may have a an effective shorted turn effect if you have a cover over it touching the main chassis.

No metallic parts are present,and secondaries are no connected...

It sounds like it may have an internal short. Do you have access to a variac (variable transformer)? This way you can apply the power slowly and avoid the inrush current and check for results.
