Table 5-4: Colour coding and configuration are assigned as per IEC 60 309-2 pin and sleeve
standard that makes the mating of plugs and receptacles of different voltages and
frequencies impossible.
1) Chiefly for ship’s wiring
2) Frequencies
≥
100 Hz lead to higher heating behaviour. This must
be compensated by a max. ambient temperature of
≤
40 °C, a T5
temperature class or a reduction of current to 25 A.
