5-Pin 400V Gas Tube protector

Porta Systems gas tube modules are dependable plug-in devices that guard sensitive telecommunications systems from dangerous voltage surges. The gas tube utilizes a three-element sign. This prevents destructive line-to-line over voltages, protecting PBX’s and key systems in a way that conventional two-element gas tubes cannot. The modules include heat activated fail-safe mechanism that provides additional protection against power crosses. Test points allow easy test access to the outside plant.
