Raycap / ISKRA Surge Protection

ISKRA Zascite was founded in 1989 in order to develop and produce surge protection devices for various applications of protecting electrical and electronic appliances in industry, business facilities and people’s homes. Despite a number of different technologies which have been appearing on the market in the field of surge protection devices, Iskra Zascite has remained loyal to varistor technology and thus contributed its part to the development of this particular technology. The company also provided guidelines for the development of varistors which represent the main basic components of modern surge protection devices.


October 2015 Raycap (www.raycap.com) acquired surge protection manufacturer and innovator, Iskra Zascite in Ljubljana, Slovenia. Raycap is a global manufacturer with Headquarters in Munich Germany and sales and operations throughout Europe and North America. The company manufactures surge protection products and connectivity solutions for telecommunications, energy markets and other industrial applications. Raycap’s innovative technology is marketed under its Strikesorb®, Rayvoss® and ACData® product brands.
