3.2. Ringing mode
Figures 14 and 15 show that the remaining
overvoltage does not exceed +/- 260 V. The
3.2.1. Lightning simulation test
CLP200M switches on within 0.7 µs and with-
Lightning phenomena are the most common surge
t(s) ^{causes. The purpose of this test is to check the ro-}
bustness of the CLP200M against these lightning
c strikes.

Consequently, the CLP200M totally fulfills this test.
3.2.2 Power induction
(Test 3a and 3b table 2/K20)
Surges of long duration with medium voltage value
are mainly produced by the proximity of a sub-
scriber line with an AC mains line or equipment.
The purpose of this test is to check the robustness
of the CLP200M against these capacitive coupling
disturbances.
