As an option a DC-switch can be selected for this module and occupy one seat of the
two-seat RX 2 terminal base.
If your application does not have any use for the DC-switch, the RX 2 terminal base can
with advantage be used for tripping relays and eliminate the cost of an additional rack.

The test switch RTXP 24 makes it possible to test relays in a fail-safe way. Inserting
test-plug handle RTXH 24 into the test switch automatically prepares for testing in
proper sequence. Blocked trip circuits, short circuited CT’s, opened voltage circuits
make the relay terminal available for secondary injection testing.
