Constructive characteristics

Two identical secondary winding intended for serial or parallel connection (jumpers supplied with the transformer)

Windings in F(155°C) or H(180°C) thermal class

Flexible insulation Class B(130°C) or F(155ºC)

Impregnation Class B(130ºC) or F(155°C)

Great capacity clamp type terminal blocks:

25VA | 40VA > 4mm² (max. torque 0,5Nm)
63VA...320VA > 10mm² (max. torque 2Nm)
400VA...1000VA > 25mm² (max. torque 2,5Nm)
1300VA...3000VA > 50mm² (max. torque 4Nm)

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

Fixing on symmetric rail in rated power up to 320VA
