Littelfuse, Inc. Three Terminal Maximum Duty Gas Plasma Overvoltage Arresters (GDT) SL1026-400

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. 55 kA surge capability (single shot) tested with 8/20µS pulse as defined by IEC 61000-4-5 40kA surge capability (repetitive) Will protect against Trapezoidal waveforms as specified in RIA 12. Will protect against capacitor discharge voltage transient waveforms as specified in RIA 12. Will protect against double exponential voltage transient waveforms as specified in IEC 571.
