1
Maximum working voltage (DC or AC peak) measured at
< 10 µA leakage for ESP TN/JP and ESP TN/RJ11 products and
5 µA for ESP ISDN/RJ45 products.
2
Maximum working voltage is 5 V for pairs 3/6 & 4/5, and
58 V for pairs 1/2 & 7/8.
3
The maximum transient voltage let-through of the protector
throughout the test (±10%), line to line & line to earth, both
polarities. Response time < 10 ns.
4
Test to 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).
5
The first let-through voltage value is for pairs 3/4 & 5/6, and
the second value is for pairs 1/2 & 7/8.
6
The installation and connectors external to the protector may
limit the capability of the protector.
