SMC Metal Oxide DC Surge Arrestors provide surge protection for DC distribution systems in
transit, industrial and mining applications. The arrestors can be mounted in rectifier
substations at the DC feeder, on catenary poles, at the power rail or on a vehicle. The
unit should be mounted as close as possible to the devise it is protecting. The arrestor
and devise should be connected to an appropriate sized ground for anticipated surge leads.
Arrestor selection is based on line to ground maximum continuous operating voltage(MCOV).
The DC Surge Arrestors utilize metal oxide technology, that has been proven in station and
intermediate class arrestors. They are designed to operate in temperatures not exceeding
60°C. The arrestor housing is manufactured of impact resistance UV stablized polyestor
glass compounds with the element encapsulated. The element's encapsulated area also has a
high dielectric sleeve for added protection. The unit is sealed with a stainless steel
cap. The connecting studs and mounting hardware are manufactured from corrosion resistance
stainless steel. Energy discharge capacity is 2.6 kJ/kV for current < 500A.
