Klüberlectric KR 44-402 is a special lubricating grease developed for electrical switches, contacts and sensors. Contains UV indicator for quality control when applied locally in small amounts with synthetic hydrocarbon oil and lithium soap. Klüberlectric KR 44-402 is particularly suitable for lubricating electrical contacts with its special additive combination. It is especially designed for the protection and lubrication of copper, tin and silver surfaces against corrosion. Other positive effects are reduced disassembly, insertion and switching forces, reduced crater and oxidation formation, longer number of switching and connecting cycles, constantly low contact resistance and smooth switching transitions.
