4.1 Digitrip RMS 510
The Digitrip RMS 510 Trip Assembly consists of a Digitrip
RMS 510 Trip Unit described in I.L. 29-885, auxiliary current
transformers (3 or 4), a stab-in trip unit edge connector and
a test terminal block with test receptacles for external field
testing mounted in the breaker (Figures 4 and 5).
4.2 Digitrip RMS 610
The Digitrip RMS 610 Trip Assembly consists of a Digitrip
RMS 610 Trip Unit described in I.L. 29-886, auxiliary current
transformers (3 or 4), a stab-in trip unit edge connector, a
test terminal block with test receptacles for external field
testing and a Power/Relay Module mounted as shown in Fig-
ures 4 and 5. The Digitrip RMS 610 Trip Unit performs all the
functions of the Digitrip RMS 510 Trip Unit and, in addition,
has a four character display, three phase and one ground
(when supplied) current pointer LEDs along with a stepping
pushbutton as outlined in Table 1.
The Power/Relay Module requires a 120 V, 50/60 Hz, 6 Va.
control power supply for operating the readout display and
internally mounted signal relays. It provides signal contacts
for three remote mode of trip indications and a high load
remote alarm. The relay contacts are each rated 120 V, 50/60
