Line-to-Ground Lightning Protection Assembly using a high energy Gas Discharge Tube
The Model SSS-G145CB provides Line-to-Ground Lightning Protection on lower voltage power and signal line pairs with a Line-to-Line voltage limit of 20VDC
or 14VRMS (AC) [i.e. nominal 12VDC power feeders are one application]
Note: This device replaces the Model SSS-G145 and SSS-G145NI. This device is electrically identical
to the SSS-G145 and SSS-G145NI. However, the Gas Discharge Tube is mounted to a printed circuit board that emulates the footprint of a
standard lightning arrester. The circuit board mounting provides a rugged and highly reliable device. Please
contact us
if you are interested in the SSS-G145 or the SSS-G145NI as we can make them.
Components are mounted to a printed circuit board that is form and fit compatible with a standard lightning adapter
High-Energy Gas Tube Arrester Protection rated for 20kA discharge
High-Energy Gas Tube provides air gap isolation
Gas Discharge Tube is UL Listed
Robust and cost effective Line-to-Ground Protection solution for low voltage signal, power, and communication
Features:
Mounts on standard AAR terminal blocks (not supplied) with 2-3/8" center-to-center post dimensions (standard for lightning arresters)
or any AAR terminal block strips that are positioned to accept a standard lightning arrester spacing
Utilizes open slots at the ends of the circuit board for mounting flexibility and easy maintenance
All copper traces are on the underside of the board to prevent accidental shorting
Connection to the AAR Posts is on the underside of the circuit board
Used as Line-to-Ground protection on Line Pairs whose Line-to-Line Voltage does not exceed 20VDC or 14VRMS
Not for track-wire Line-to-Ground protection
