The TDX100C Compact Series of Transient Voltage Surge Suppressors is designed
for critical protection applications. The 100kA 8/20s of surge protection exceeds
the IEEE
®
C62.41.2 Scenario II single-shot surge rating requirements for exposed
service entrance locations Exposure 3.
The NEMA
®
-4 weather tight housing allows the TDX to be installed on indoor or
outdoor service panels. The preconfigured connecting leads simplify installation.
The unique narrow construction allows the SPD to fit between adjacent panel
boards and connect via a 90-degree elbow. A flush mounting kit is also available
for installing the SPD in drywall applications. E566S
