Make before break base - Injection with ESSAILEC RJ45 test plug
®

3. Preparation: Test plugs connections
3.2 The ESSAILEC RJ45 test plug has
®
built-in dia. 4 (1) and RJ45 test sockets (2)
in order to simplify the test operations. They
allow current and voltage sensors
2
measurement (1) as well as injection to the
protection relay (2).

3.1 The test equipment is equipped
with dia. 4 test plugs.

4. Test phase: Make before Break
When the plug is fully inserted
in the socket, inner mobile
contacts (3) are pushed down
by plug’s plastic leads (4) and
3 circuits are opened. Signals are
3 4 derived into the dia. 4 plug

Preparation: towards the test set.
It is possible to perform
Test plugs
connections simultaneously current and
voltage sensors measurement.
