trip units are

digital, rms sensing, electronic trip units with an LCD
and keypad for viewing and/or changing the various
function settings. Refer to User’s Manual GEH-702
for detailed information concerning the operation,
adjustment, and setting of the breaker trip unit.

You should record the overcurrent protection and
protective relay set points for future reference.

NOTE: Trip units as received may have settings that are
undesirable for the specific application. Ensure that
settings are appropriately adjusted before energizing
the breaker.

Operation
The circuit breaker status is indicated by ON/OFF
markings, universal I/O symbols, and an indicator
window that shows red for ON, yellow for TRIP, and
green for OFF. The corresponding handle positions are
illustrated in Figure 2. To close the breaker from the
OFF position, move the handle to the ON position. To
close the breaker from the TRIP position, first move the
handle to the OFF (reset) position, and then back to the
ON position.

A Push-To-Trip button is provided for convenience in
testing the mechanical operation of the breaker.
