RXME 1 used as a trip contact re-enforcement
When single pole tripping is used one RXME 1 is required
per phase and of course per subsystem in redundant
systems.
Lock-out can be arranged with RXMD 1 remanence relay
activated from binary outputs on IED and possible other
protection relays required to activate lock-out, see figure
The contact of RXMD 1 is connected to open the closing
circuit to the breaker closing coil. Another contact can be
used to light-up a lamp push button to have indication of the
lock-out and then reset with the push-button. It is
recommended to avoid trip contact latching as this will
mean problem for example with trip circuit supervision and
further at failing breaker, mean that the trip coil is burnt and
the trip coil DC supply is tripped. The most important is to
prevent that the breaker is closed at persistent faults.

Push button and selector switch
SEMOD121142-4 v2
The push button is available with or without pilot lamp and
with one or two buttons. It is used to reset the lock-out
relays when an external independent lock-out and lock-out
indications is required. The push button unit can also be
used as a local selector of Auto-Reclose operation when
this is required to be done locally as well as through
communication.
The selector switch is available with two or three fixed
positions and with different contact combinations. Selector
switch can e.g. be used as Local/Remote selector or as a
local selector of Auto-Reclose operation. See section
for reference to more detailed
information.

Supervision relay
SEMOD121154-4 v2
The relay RXEM1 can be used to detect for example loss of
DC voltage supply or to detect open circuits. A typical
application is continuous supervision of a circuit breaker trip
circuit, including the breaker coil. See section
for reference to more detailed information.

7. Connectors
M2006-3 v3
The connectors are used for analogue signals and binary in-
and output signals.
Use the ferrules to connect two wires to the same terminal
point of a connector of screw compression type. Note that
1.5 mm
2
is the maximum dimension allowed on these wires.
An appropriate crimping tool is needed to apply the ferrule
