Operating Data

Operating Data for collective Tracks in Cu complies DIN 43671 and Aluminum complies DIN 43670

One track per conduct, AC at 60 Hz, environmental temperature 35 °C increasing by 30 °C. Two parallel utilized collective tracks with small distance to each other cannot collectively calculated for a double current but only 1.7 times the current for one track.
Please, see also DIN 43670 and DIN 43671.

Operating Data for Cu Braid and Cu braid Bands

Starting environmental temperature at 35 °C increasing to temperature max. at 70 °C
