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 
Hz, 1.0 A.

Effective July 2010
