HY5WS-17/50 Surge Arrester

Surge arresters HY5WS-17/50（ Equivalent to  OPN-P-10)  are designed for outdoor use in temperate and cold climates at temperatures from minus 60 to plus 60 degrees C.
and electric arc furnaces), with increased capacitive currents during single-phase short circuits to earth. The arrester is a support-type protective device consisting of series-connected metal oxide varistors without series or parallel spark gaps, enclosed in an insulating housing. The surge arrester provides effective protection for low-voltage overhead lines, distribution transformer substations, and residential and industrial building branches. This arrester is installed in a 50 Hz AC network with an isolated or compensated neutral.
