Protect your communication equipment from the unpredictable with the Protection Series. This Telephone Lightning Arrester is designed to intercept high-voltage surges and lightning strikes traveling through your phone lines. It is the definitive solution for safeguarding your telephone handsets, fax machines, and DSL modems from permanent electrical damage.
Passive Protection: Requires no external power to operate; it sits silently on your line and only activates when a dangerous voltage spike is detected.
Zero Signal Interference: Specifically tuned for analog and digital voice frequencies, ensuring your call quality and internet speeds remain unaffected.
Durable Earth Connection: Features a dedicated external grounding wire to ensure that surge energy is successfully discharged away from your electronics.
Main Line Entry: Install at the point where the external telephone service wire enters your building.
Sensitive Equipment: Connect directly before expensive hardware like high-end fax machines or multi-line PBX systems.
Rural or Elevated Areas: Essential for homes or offices in areas prone to frequent thunderstorms and lightning activity.
Server Rooms: Protect your DSL or VDSL modems to prevent surges from jumping into your local network via the router.
Standard RJ11 Interface: Universal 4-wire (6P4C) compatibility that works with almost all home and business analog lines.
In-Line Design: Features a "Line In" and "Equip Out" port for simple, series-based installation.
Flame-Retardant Housing: Built with high-impact, UL-rated materials to ensure safety even during a catastrophic electrical event.
Automatic Reset: Unlike a fuse, the arrester resets itself after a surge passes, providing continuous protection for your next call.

1. Does it work without the ground wire? No. The ground wire is the most important part. Without connecting it to a proper electrical earth (like a copper ground rod or a grounded metal frame), the surge has nowhere to go and will still hit your equipment.
2. Will this protect against a direct lightning hit? While no device can guarantee 100% protection against a direct strike, this arrester significantly reduces the risk and protects against "induced surges" (strikes hitting nearby lines), which are the most common cause of fried electronics.
3. Does it affect my ADSL/VDSL speed? These are designed with low-capacitance components to ensure they don't "dampen" the high-frequency signals used by high-speed internet. Your sync speed should remain stable.
