AC surge arrester | 4P | 420V | T2 | C

Description: Protect your goods and your family - invest in securityEvery circuit of an electrical installation must be properly protected from the effects of overload and short-circuit, so it is obligatory to use appropriate protection. One such device is a surge arrester, also known as a protector or lightning arrester, which lowers the voltage spike and brings it to ground. Arrester effectively eliminates the risk of damage to the installation caused by a transient overvoltage, short circuit or lightning strike, which can damage the network and connected equipment.Cleverly keeps you out of dangerQoltec brand surge arresters are equipped with high voltage sensors and a 3-stage DC switch. The protection consists of a base part and plug-in protection modules. It is suitable for use in photovoltaics.
