Generally about transformers
The transformers must be protected against possible overloads and short circuits. Our transformers belong to the non-short-circuitproof
type and so they must be protected using external fuses. Rated current of the suggested fuse is always indicated on our labels.
However the protection can be also obtained using Miniature Circuit Breakers – ETIMAT. Selected protection of the input winding of
the transformer must be chosen taking into account that at the starting phase of the transfomer, a high value of inrush current is generated,
a value that can reach 25 times the value of the input rated current, for about 10 milliseconds. Hence, time delay fuses (T or aM
type) or MCB – ETIMAT having D or K characteristic must be used for a correct protection. The protection of the secondary side can be
realized using fuses of F or gG type, or MCB – ETIMAT having B or C characteristic. Here below there is a table with all the suggested
protection fuses for the input and output windings (all the values are in Ampere):
