Ruth's sister RJ45 Surge Arrester 5KA 10KA 30V 1ns .5dB -25+85C 95% humidity
Compact RJ45 surge arrester protects monitoring gear with 5 kA nominal and 10 kA maximum discharge, 30 V protection level.
- Quick 1 ns response limits surge damage
- 10 kA max discharge handles heavy transients
- Low 0.5 dB insertion loss preserves signal quality
- Operates from -25 °C to 85 °C at 95 % humidity
- Compact 9 × 3 × 2.5 cm fits tight enclosures
Network Surge Protection
The Ruth's sister RJ45 surge arrester protects monitoring equipment from voltage spikes on Ethernet lines. It suits installers who need a compact, CE-certified protector for coaxial video-signal circuits in harsh environments. The device fits inline without bulky enclosures.
Single-Line Protection Circuit
The unit uses a single line-to-ground protection circuit with a nominal discharge capacity of 5 kA and a maximum of 10 kA. A voltage protection level of 30 V and a 1 ns response time clamp transients before they reach sensitive gear. Insertion loss is only 0.5 dB.
Wide-Range Thermal Operation
Rated for continuous use from -25 °C to +85 °C at up to 95 % relative humidity, the arrester maintains its clamping performance without active cooling. Its passive electronic-component construction generates no audible noise and draws no measurable standby power.

Questions about this item
What does the 10 kA maximum flow capacity mean for my network gear?
It is the highest surge current the arrester can divert once, tested with an 8/20 µs waveform, so a direct lightning-induced spike up to that level is clamped before it reaches connected equipment.
How does the RJ45 interface and 1 ns response time limit what the device can protect?
The RJ45 port passes Ethernet signals while the 1 ns response clamps transients faster than most switching edges, capping let-through voltage at 30 V for lines referenced to ground.
What physical space and mounting does the 9 cm by 3 cm by 2.5 cm body need?
The compact inline housing fits in a cable run or panel cut-out and operates from -25 °C to +85 °C at up to 95 % humidity without additional brackets.
