RoHS Pb Greentube™ SL1026 Series Gas Plasma Arresters

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 con-

nection. 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.
