The multichannel earth leakage relays COMBI 6 have been designed for the monitoring and protection of up to 6 independent systems. A single instrument which is 3 DIN modules wide, saves DIN rail space inside the enclosure. The terminal blocks are two part which allows for ease of wiring. The 4 front keys allow for easy programming, further simplified by the copy/paste function available in the settings menu.  A push button dedicated to the Scroll of the channels allows selection of the input to be displayed. In the case of a trip intervention, the display will automatically show the last tripped channel, and the corresponding LED will be ON. It is available in 3 versions: Type B only - Type AF only - mixed B / AF with 5 different input combinations (1-5 / 2-4 / 3-3 / 4-2 / 5-1)
