The Digitrip RMS 51 0 Trip Unit is completely self-con

tained and when the circuit breaker is closed, requires no

external control power to operate its

protection sys

tems.

It operates from current signal levels and control

power derived through current sensors integrally

mounted in the circuit breaker.

The Digitrip RMS 510 Trip Unit is available in six different

types. Each trip unit may be equipped with a maximum of

five phase and two ground (time-current) adjustments to

meet specific application requirements. The types of pro

tection available for each model include the following,

which are illustrated in Figures 2.1 through 2.6:

Note*: RMS Digitrip Type Ll, LS, and LSI trip units
can be applied on 3-pole or 4-pole circuit breakers for

protection of the neutral circuit,

IF the circuit breaker

is wired and MARKED for NEUTRAL PROTECTION.

Refer to the National Electric Code for appropriate

application of 4-pole breakers.

1 .2 Information

Light Emitting Diodes (LED's) on the face of the trip unit

light "Red" to indicate the reason for an automatic trip

operation. The battery in the rating plug maintains the

reason for trip indication following an automatic trip oper

ation, until the "TRIP RESET" button is pushed.

The "Green" LED in the lower right corner "blinks" to indi

cate the trip unit is operating normally. The battery in the

rating plug is "OK" if the LED lights "Green" when the

"battery check" button next to it is pushed. (See

Section 6.).

Note: The Digitrip RMS 510 provides all of its protec

tion functions regardless of the status of the battery.
The battery serves only to maintain the indication of
the reason for automatic trip.
