You are looking at the mating face of the ceeform socket.
Used to use 3 pin yellow connectors, but now uses 4 pin yellow connectors, since the HSE were informed that the German safety authority TUV was very concerned about use of the earth pin on the 3 pin connector for something other than a protective conductor. It was being used for the control Voltage in some hoists and was during operation at 110V. PCM, the PSA and the HSE were involved in obtaining permission to use a plug and socket system for the control of an Electro-Mechanical device. TUV wanted a completely different solution.
The 16amp version plug is available in a 'stackable' format where it has a matching socket on it's rear.
