Standards

IEC/EN 61558-1 Transformers, general specifications
IEC/EN 61558-2-1 General use transformers
IEC/EN 61558-2-2 Control transformers
IEC/EN 61558-2-4 Isolating transformers
IEC/EN 61558-2-6 Safety transformers
RoHS Compliant

Constructive characteristics

Windings in F(155°C) or H(180°C) thermal class
Flexible insulation Class F (130°C)
Impregnation Class F (155°C)
Connections with accidental contact protected terminal blocks
Screw earth connection (standard IEC/EN61558 prescribes in the clause 24 that it should not be possible to loosen the protection wire without the aid of a tool)
TIG welded magnetic core prevent vibration and allows small air gap to reduce the magnetization current
