Test

Type tests
All technical data specified, such as current ratings and temperature rise, insulation resistance, voltage and short circuit withstand, have been certified in accordance with international standards (IEC, VDE or BS) by the independent testing stations K.E.M.A., LABORELEC, LCIE. Assembled elements with cast junctions were submitted for type testing.
