The multichannel earth leakage relays COMBI 6 have been designed for the monitoring and protection of up to 6 independent systems. A single 72x72 instrument enables considerable optimisation of panel space and wiring connections. The terminal blocks are two part which allows for ease of wiring. The 4 front keys allow immediate 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, and mixed B/AF, with 5 input combinations. |
