je pense que tu as tort, car il ne s'agit que de ça:
CLIFFCON 4 Pole Connector
Our range of 4 pole Cliffcons, available in straight or 90° versions have now been designated Low Voltage (coloured Blue) and High Voltage (coloured Red).
Cliffcon Blue (LV) is for uses under 120V AC such as speakers, amplifiers, battery chargers, vehicle use. Max current / pole 20a. (30A.)
Cliffcon Red (HV) is for uses up to 250V AC such as lighting and power connections. Max current 20A. (30A.)
Only plugs and sockets of the SAME colour are compatible, so red plugs cannot be plugged into blue sockets, and vice versa. This allows use of both kinds of connector on the same equipment, with no chance of mismatching of connections. Convenient Faston / Screw / Solder connections. Chassis connectors are air tight and fit the same cut-outs as XLR connectors.
Our original black version remains available. However, we suggest users change to the HV / LV versions for new designs.
CLIFFCON 8 Pole Connector
Our 8 pole Cliffcon is primarily intended for use in lighting applications. Rated max 30A 250V AC. It can be used for any industrial application which needs a touchproof connection system of up to 8 pole. General features are similar to our 4 pole version. 8 pole is only made in one 90° black version. A dust cover is available for the chassis socket. Connections to the socket may be made by soldering or faston receptacle, and to the plug by soldering or screw.
