LK-BZ-3 G Signal Lamp used for optical signaling of voltage on individual phases of a three-phase network.

The controls are protected by fuses connected in series with them, which avoids the use of an additional module with protections and, consequently, saves space in the electrical panel. The other end of the fuse is brought to the connector of the device's casing, which allows it to also be used to protect other parts of the circuit.

The presence of voltage downstream of the fuse is indicated by the illumination of the corresponding LED diode connected to the circuit of that phase. In case of phase voltage loss or a blown fuse, the indicator light is off, indicating the absence of voltage.
