About eaw Relaistechnik
EAW Relaistechnik GmbH develops, produces and distributes relay technology at its site in Königs Wusterhausen, Brandenburg. The company was founded in 1926 as Elektro-Apparate-Werke Berlin by AEG and continues this tradition today. The portfolio comprises thermal relays as thermal switches, thermal sensors (PT, PTC, NTC and KTY sensors), switching and signaling relays (RELOG, RA70), low-voltage switchgear such as air contactors and vacuum contactors, as well as temperature control systems for liquids in heating technology. The offering is complemented by functional test rigs for thermal relays as well as engineering and retrofit services; the sister company eaw Automation GmbH supplies digital machine controls and software development. The products are used in the automotive industry, by energy suppliers, in railway systems, mining, household appliances, heating and air conditioning technology, aviation, shipbuilding, wind power and crane construction. EAW covers the entire value chain from development through production to distribution and delivers worldwide, including to China, Europe, America and Africa.
