Dehn 40KA 600VDC Type 2 Surge Arrester 950531

The surge arrester is a tool that can be mounted inside the electrical panel, i.e. upstream of the house installation. Its use allows the electrical system on which it is installed to be protected.

The surge arrester will protect the entire system from surges, surges and spikes of electricity that may come from the power line operator, or from atmospheric phenomena such as lightning. These power anomalies can cause serious damage to devices connected to sockets.

A power surge can cause the hardware of a PC to break, or short-circuit the boards of smartphones, tablets and household appliances. In the event that the flow of energy suddenly increases, human life may even be at risk due to electrocution. To prevent this from happening, it is therefore advisable to fit a surge arrester.
