Power indicator 230V/400V LED red/green/yellow TN Type: LKM-01-40 EXT10000039

Three-phase power monitoring – LED indicator LKM-01-40

This power indicator, designated LKM-01-40, is a simple and effective solution for visually monitoring the presence of voltage in three-phase TN networks (with neutral conductor N). Signaling is done using three bright LEDs, marked L1, L2, and L3, allowing for quick identification of any problems with individual phases.

#### Functionality and application

This indicator is particularly useful in electrical installations where reliable power status monitoring is crucial. Thanks to optical signaling, installers and users can easily check if all phases are active. It can be used both in new installations and for modernizing existing systems. Signaling with three LEDs allows for quick diagnosis of problems with individual phases – the absence of light from one of the LEDs indicates a lack of voltage on that phase.

#### Installation and design features

The LKM-01-40 indicator is designed for easy mounting on a standard TH 35 rail. Its compact, single-module housing saves space in the distribution board. The use of high-emission LEDs ensures good visibility even in low light conditions. In addition, the LEDs are characterized by high durability, which translates into a long service life of the device and minimizes the need for replacement.
