1
Maximum working voltage (DC or AC peak) of telecom/data protection measured at <10 µA leakage for ESP MC/TN/RJ11 and 1 mA for ESP MC/Cat-5e.
2
Maximum working voltage is 5 V for data pairs 1/2 & 3/6.
3
The maximum transient voltage let-through of the protector throughout the test (±5%), phase to neutral, phase to earth and neutral to earth.
4
The electrical system, external to the unit, may constrain the actual current rating achieved in a particular installation.
5
Combination wave test within BS EN/IEC 61643, IEEE C62.41-2002 Location Cats C1 & B3, SS 555:2010, AS/NZS 1768-2007, UL 1449 mains wire-in.
6
The maximum transient voltage let-through the protector throughout the test (±10%), line to line & line to earth. Response time < 10 ns.
7
Test to BS EN/IEC 61643, IEC 61000-4-5:2006, ITU-T (formerly CCITT) K.20, K.21 and K.45,Telcordia GR-1089-CORE, Issue 2:2002, ANSI TIA/EIA/IS-968-A:2002 (formerly FCC Part 68).
8
The interfaces used in Cat-5/5e systems incorporate an isolation transformer that inherently provides an inbuilt immunity to transients between line and earth of 1,500 Volts or more.
9
The installation and connectors external to the protector may limit the capability of the protector.
