This device is essential for electrical switchboards, ensuring reliable monitoring of power availability in industrial and residential installations.

## Long description

The Zamel LKM-05-40 is a modular power supply indicator engineered for the precise monitoring of 230V AC voltage within TN electrical networks. This device serves as a critical component for electrical switchboards, offering immediate visual feedback on the status of power supply phases through its integrated LED display. By providing a clear indication of voltage presence, it helps maintain operational safety and efficiency in both residential and industrial electrical systems.
Advantages
The primary benefit of the Zamel LKM-05-40 lies in its high-visibility LED signaling, which allows for rapid status assessment at a glance. Its modular design ensures seamless integration into standard DIN-rail switchboard configurations, saving space and simplifying installation. The device is built for reliability in continuous monitoring applications, ensuring that any loss of phase or power supply issues can be identified immediately, thereby reducing downtime and enhancing the safety of the electrical infrastructure.
Suitable for
Monitoring power supply phases in residential electrical distribution boards.
Industrial control panels requiring constant voltage status indication.
TN network installations where phase presence verification is essential.
Electrical switchgear maintenance and diagnostic setups.
When it may not be suitable
This device is specifically designed for 230V AC TN networks and is not compatible with DC circuits or non-TN network configurations. It should not be used in environments where the voltage exceeds the specified operating range or in locations with extreme environmental conditions that fall outside the manufacturer's technical specifications.
Key specifications
Operating voltage: 230V AC.
Network compatibility: TN systems.
Indication type: LED (Yellow, Green, Red).
Mounting: Modular DIN-rail.
Application: Phase status monitoring.
How to use
The Zamel LKM-05-40 should be installed by a qualified electrician in accordance with local electrical safety regulations. The device is designed for mounting on a standard DIN rail within an electrical distribution board. Once mounted, the input terminals must be connected to the corresponding phases of the 230V AC TN network. After the power is restored, the LEDs will illuminate to indicate the presence of voltage on the respective lines.
What to consider before purchase
Verify that your electrical system is a 230V AC TN network.
Ensure there is sufficient space on the DIN rail within your distribution board.
