Protection Loss of neutral : NMP-05D
With the arrival of the Smart City, there are more and more electronic devices connected to the networks of cities. However, during road works or due to a connection error at the electrical outlets, the installations can be subjected to an over-voltage higher than 300V (so-called neutral break). Electronic devices may be damaged. The cost of replacing damaged equipment and the cost of the intervention can be very expensive for the city.
Lumnex offers a protection box: NMP-05D (Neutral Missing Protection) to be placed upstream of the devices to be protected. When an over-voltage occurs on the network, the NMP-05D turns off the supply voltage with its built-in relay.
As soon as the problem is resolved (neutral cut-off correction), the NMP-05D automatically turns on the equipment. For more details see the technical sheet.
