2.3 Ringing mode
In ringing mode (Ring relay in position 2), the only
protection device involved is the CLP30-200B1.
In normal conditions, the CLP30-200B1 operates
in region 1 of
A1
curve, and is idle.
If an overvoltage occurring between TIP (or RING)
and
GND
reaches
the
reference (+/- 200V), the CLP30-200B1 acts and
the line is short-circuited to GND. At this time the
operating point moves to region 2 for positive
surges (region 3 for negative surges). Once the
surge current disappears, the device returns to its
initial state (region 1).

For surges occurring between TIP and RING, the
CLP30-200B1 acts in the same way. This means

tripolar
When used alone, the CLP30-200B1 acts at the
internal overvoltage reference level (+/- 200 V).
Furthermore, it is possible to adjust this threshold
level to a lower voltage by using up to 4 fixed
external voltage reference (V
Z1
to V
Z4
) (see fig.5).
