Control lights LK-BZ-703
The LK-BZ-703 indicator lights are used to provide visual indication of the presence of voltage in the individual phases of a three-phase mains supply.
Lights with built-in protection.
The LK-BZ-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) saves space in the switchboard. Each indicator is protected by a built-in fuse, which eliminates the need for an additional protection module.
Operation
The presence of voltage in a phase is indicated by the corresponding LED lighting up in the circuit for that phase. If the LED is not lit, this indicates either a lack of supply voltage or a fault in the built-in fuse element.
The fast-acting fuses built into the indicator light eliminate the need for additional protection when the light is installed in a circuit with a current rating of less than 100A.
