The Lovato type 2 20kA 1P+N cartridge-based surge arrester SG21NA300 is ideal for providing effective protection and ensuring the correct functioning of electrical systems in different environments, such as homes, offices and industrial plants. This tool protects the system from surges and electricity surges that can cause damage to devices and sockets.
Surge arresters are divided into three classes:
Class 1: we find devices to be used in areas where adverse atmospheric phenomena such as thunderstorms and lightning usually persist (for example in the mountains).
Class 2: there are surge arresters that protect the system from surges and peaks caused by maintenance work on the line.
Class 3: instead we find those devices that offer even greater protection: in this case the surge arrester is installed directly in correspondence with the electrical sockets present in the house.
