Signal lamps LK-703
The LK-703 indicator lights are used to provide visual indication of the presence of voltage in the individual phases of a three-phase mains supply.
The compact size of the housing (6.2 mm wide) helps to save space in the switchboard.
The presence of voltage in a phase is indicated by the corresponding LED in that phase’s circuit lighting up.
If an overcurrent fuse rated at 25 A or more is installed upstream of the lamp’s connection point to the mains, the lamp’s connection circuit must be protected by a fuse rated at no more than 6 A.
