It is an open circuit until impinging high voltage enters an ionizes the gas inside which creates a low impedance presumably to ground. Only useful in a lightning incident (nearby or direct hit). If the latter then you are fundamentally screwed. I have photos to probe it. Message: if lightning is near (or predicted) then simply disconnect everything. Let us ALL float. I’m talking antennas, AC power cord and ground wires **Q: Does this device support 24v passive poe?** A: YES , this will easily support 24volt passive or non-passive POE. Normally POE is 48volts on power injectors or network switches. I know that it will support over 60 volts, as to smart 3 lens outdoor cameras that i have installed at Banks. This is , if you ground the DIN rail correctly to allow gas discharge tube to function properly to protect equipment. Gas discharge tube opens and closes data circuit, with no ground it will just act as a fuse and burn up after lightning strike. I always use TWO ethernet surge protectors , one on network switch rack and one upon entry into building with both TWO DIN rails grounded. Daniels Data Inc. - Dallas,TX - John Daniels **Q: How long of a rail do you need? What is the shortest length that I can use?** A: It mounts perpendicular to the dinrail so about 1” is minimum. I’d use enough too have two acres in the rail though or it will rotate. ## Frequently Bought Together - Ethernet Surge Protector - PoE+ - Gigabit - (with DIN Rail Mount Option) - Gas Discharge Tube for Full Protection - RJ45 Lightning Suppressor - LAN Network CAT5/CAT6 Thunder Arrestor - Tupavco TP309 - 12V-110V DC Miniature Circuit Breaker, 15 Amp 1 Pole Battery Breaker Protector for Solar PV System and RV, Thermal Magnetic Trip, DIN-Rail/Surface Mount, Chtaixi DC Disconnect Switch B15 - Chtaixi AC Miniature Circuit Breaker, 16 Amp 120V/240V 2 Pole DIN Rail Mount Circuit Breaker, Thermal Magnetic Trip, Solar AC Disconnect Switch MCB C16 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/110057903-din-rail-ethernet-surge-protector-tupavco-tp309](https://www.desertcart.vn/products/110057903-din-rail-ethernet-surge-protector-tupavco-tp309) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-09-06*
