You are only a single contact operation away from picking up the trip coil then, so you trip speed is the speed of your motorized sf6 gas pressure switches plus one contact.Get price

Austrian SS - Wikipedia

HistorySee AlsoReferencesThe term "Austrian SS" is often used to describe that portion of the SS membership from Austria, but it was never a recognized branch of the SS. In contrast to SS members from other countries, who were grouped into either the Germanic-SS or the Foreign Legions of the Waffen-SS, Austrian SS members were regular SS personnel. It was technically under the command of the SS in Germany, but often acted independently concerning Austrian affairs. The Austrian SS was founded in 1930 and, by 1934, was acting as a covert force to bring about the Anschluss with Germany, which occurred in March 1938. Early Austrian SS leaders were Ernst Kaltenbrunner and Arthur Seyss-Inquart. Austrian SS men were organized under the same manner as the Allgemeine-SS, but operated as an underground organization, in particular after 1936 when the Austrian government declared the SS an illegal organization. Kaltenbrunner, for example, repeatedly made trips to Bavaria to consult with Himmler and Heydrich. Hiding on...Get price
