What are the key design requirements of a surge arrester?

Gapless metal-oxide design using non-linear metal-oxide resistors for effective overvoltage protection.

Outdoor climatic durability designed for reliable operation under UHL1 placement conditions.

Pressure relief protection with a built-in pressure relief device to minimize the risk of housing rupture during fault conditions.

Tested and documented performance, including electrical characteristics, energy capability, mechanical strength and overall dimensions.
