Kraus & Naimer, a world leader in industrial switch design since 1907, introduced a range of enclosed switches suitable for the harsh Australian conditions more than 25 years ago. Since 1988, millions of KS/KT/KL enclosed switches have been sold in Australia and around the world. They have been used very successfully in a huge range of applications from solar PV, to refrigerated warehouses at -40°C and in tropical areas at temperatures up to 70°C. They have performed flawlessly under dry, wet and humid conditions. The enclosures are IP66/67 and IK07 rated. Kraus & Naimer is accredited to ISO9001 and has strict quality control procedures throughout the entire manufacturing process to ensure the highest quality and reliability. Kraus & Naimer not only use accredited independent test labs to ensure that products comply with the relevant standards, but also have in-house facilities to test products in real life situations as well. “The enclosures for these switches are designed for high performance in a wide range of environmental conditions. They are made from UV stabilized plastic material with stainless steel lid screws and have no failures reported”, says Reinhard Gansfusz International Sales Manager from Kraus & Naimer, “Our enclosures have been mounted on panels in the K&N real life testing facility for over 20 years and are still in excellent condition. Function testing of these enclosures is carried out regularly. I have even seen enclosures mounted on chair lift pillars at altitudes of more the 2500 m and none of them are damaged”. Kraus & Naimer enclosed AC switches have been installed outside under harsh Australian conditions with no structural degradation. Five years ago, Kraus & Naimer expanded upon this popular range of enclosed switches by adding a range of DC Isolators designed specifically for the solar industry in Australia and New Zealand. Isolators tested for longevity 20 years on the roof of Kraus & Naimer’s real life testing facility proves longevity of the product. KS/KT/KL Enclosed Switches - 43 -
