REL, REB and REC provide you with a test switch module. There are two alternatives,
which depend on the use of internal or external earthing.
See (1) at figure 20 and figure 21 , RTXP is equipped with a signal contact located on
the top, right-hand housing. This contact is for the signalling of test in progress which
is very important, especially during the test of differential protections. The contact is
wired with two 10 A terminal sockets.
