Screw Terminal Station Protectors, Screw Terminal, TandAction™ Hybrid protection

Part Number: SPD 356-XY

The SPD 356-XY TandAction™ Hybrid Station Protector employs a heavy-duty 3-element gas tube matched with solid-state MOVs (metal oxide varistors). The level of protection is improved compared to ordinary gas tube protectors by coordinating the operating voltages of the MOVs and the gas tube. The MOV operates first, providing rapid response to fast rising voltage surges, while the gas tube provides the high energy protection so important on residential telephone circuits. The result is better protection for analog and digital electronic equipment connected to the telephone network plus long protector service life.TandAction™ Hybrid Station Protectors provide improved service life even when exposed to severe temperature and humidity cycling compared to gas tubes with backup air gaps. Life shortening intermittent noise and erratic operation, due to backup air gap contamination, are eliminated with the use of solid-state MOVs. Furthermore, the heavy-duty 3-element gas tube protects against both longitudinal and metallic (transverse) surges by grounding tip and ring connections simultaneously. If a sustained power surge causes abnormal current flow on the telephone line, the fail-safe design permanently shorts the line to ground.
