Obo Surge protector 20 kA 3+NPE IP20 5095253

The surge arrester is a tool that can be mounted inside the electrical panel, thus upstream of the house system. 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 outlets.

 

A surge of electricity can cause the hardware of a pc to break, or short circuit the boards of smartphones, tablets, and home appliances. In the event that the flow of energy suddenly increases dramatically, human life may even be in danger due to electrocution. To prevent this from happening, it is therefore advisable to install a surge arrester.
