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)
