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.

Features:

  • 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

Applications:

  • Signaling equipment
  • Communication equipment
  • Control gear
  • Trackside cabinets
  • Cell phone base stations
