SL1026 Series - Three Terminal Maximum Duty Gas Plasma Overvoltage Arresters (GDT)
DataSheet:Gas Discharge Tubes SL1026 GDT Datasheet
SL1026 Series - Three Terminal Maximum Duty Gas Plasma Overvoltage Arresters (GDT) The SL1026 series is a heavy-duty transient suppresser using Gas Plasma technology. In response to a transient voltage which exceeds the fixed breakover voltage (selected according to part number) the device changes from a very high impedance state to a low impedance state, there by conducting harmful current away from the protected system. The design is optimized for the protection of electrical and electronic equipment employed in Railway systems: carefully designed geometry ensures the device does not become a short circuit in the event of a failure due to conditions and events beyond the design criteria. An electrical mounting clip (PN SL1053 ) is available to aid mounting and connection. A mounting plate (PN SL 1056) is also available which accepts 10 SL1053's. Mounting of the clips to the plate provides a common ground connection; the plate can then be connected to a suitable ground via the screw terminal.
