Key Product Benefits

• Ideal for use in control circuits or other specialized communications services using open wire, above ground cable, or buried cable
• Also recommended for use on AC circuits in conjunction with line fuses, circuit breakers or current limiting resistors
• Provides superior protection due to the rapid recovery of the three-electrode gas tube, which returns the protected line to service as the transient subsides
• Grounding termination point provides a low resistance path to earth ,ground in order to optimize protection

The 317 is an encapsulated module containing Tii’s Maximum Duty three-electrode gas tube surge arrester, engineered to protect equipment from lightning and induced surges.
