According to various measurements I found out which colors belong to the internal capacitors.
orange to brown: 2,6uF/4MΩ (serial connection of 10uF and 4,4uF)
black to orange: 4,4uF/2MΩ
black to brown: 6,0uF/2MΩ
black to brown+orange: 10,5uF/1MΩ (1000kΩ)
black to blue: 1500pF/100kΩ
This means, blue is „⏚“
Since these values can only be measured from the black cable to the blue cable, this capacitor is only suitable for devices like dust controls with power plugs that cannot be turned over when plugging in - e. g. the BS 1363 plug.
