3.3.3 - Power contact test (Test 3 table 1/K20)

The test 3 of CCITT K20 requires a serial PTC (or

fuse) which is inserted in the test circuit to limit the

current rate. This PTC acts like an open-circuit af-

ter 60 ms when a surge occurs on the line. Mean-

while, the CLP200M has to withstand the surge.

The protection device CLP200M totally fulfills this

test.
