WebProtective relays are used in industrial power generation and supply systems to open and isolate branch circuits in the case of excessive current. They are activated by means which are not dependent on a continual AC supply. They include both mechanical induction disks in older systems, and more modern electronic varieties. WebSuch relays may be actuated by d-c or by a-c quantities. Electromagnetic-induction relays use the principle of the induction motor whereby torque is developed by induction in a rotor; this operating principle applies only to relays actuated by alternating current, and in dealing with those relays we shall call them simply "induction-type" relays.

WebIn some cases, the thyristor (or the mechanical relay) may malfunction and not short-circuit the PTC. When this happens, the load is applied to the circuit and the high operating current heats up the PTC. The PTC then enters a high ohmic state, thus reducing the malfunction current to a lower level that is not dangerous. WebSENSING APERTURE. ATS SERIES - SWITCH SETPOINT. Switch Selectable 10–1200 A.
