About GRUBER Electric
GRUBER Electric was founded in 1969 by Ing. Erwin Gruber and today employs twelve staff. The company develops and manufactures custom fault-indication modules and signalling for switchgear as well as accessories for programmable controllers, including signal input and output modules and power supplies. In addition to its own manufacturing, the product range includes own product series such as the GR time and measuring relay series, GR-LED signal indicator lights, and FUTURIT signalling devices built to customer specifications. Complementing this, GRUBER Electric supports industry, control cabinet construction, plant engineering and the electrical wholesale trade with product selection, alternative evaluation and technical procurement. Cable processing (stripping and crimping) is carried out as standard on crimping and cut-and-strip machines. The headquarters is located in Kottingbrunn south of Vienna; in 2020 a German subsidiary was founded in Weißenfels.
