Power indicator protected by 3x230/400V AC 6A fuses EXT10000318-WUN

The LKM-09 power indicator module with fuse protection is designed to display the presence of supply voltage on each phase. It can also be used to protect electrical receivers against the effects of current increases above the permissible value, limited by the built-in fuses. The device is ideal even for pre-meter protection exceeding 25A. A fuse failure will disconnect the receiver from the supply voltage and extinguish the corresponding LED, making the absence of supply voltage on a given phase immediately visible. This facilitates initial diagnostics of the installation. After repairing any fault and replacing the fuse with a new one, the system returns to normal operation. It is important to note that the maximum protection current does not exceed 6A. In this configuration, the device can be used as a backup protection for control and measurement equipment, such as bistable relay sections, roller shutter controllers, or the MEW-21 energy monitor. After removing the fuse, the device provides a visible break in the circuit.
