Phoenix Contact 1 Phase Surge Arrester, DIN Rail Mount

The Phoenix Contact Surge Arrester is a surge voltage arrester consisting of a base element with a remote indicator contact and a protective plug. It features a connection in series with a varistor and a gas filled spark gap, making it suitable for mounting on NS 35/7.5. The nominal voltage is 230V AC, and it is designed for 1 channel use.

Easy testing and insulation measurement thanks to pluggable protection modules
Suitable for use in insulation monitored systems due to combination of varistor and gas discharge tube free of leakage current
Can be used in applications with increased insulation strength e.g. railway technology
