Sentinel electronic trip unit
2.1 Description
hw+ Air Circuit Breakers are equipped with a Sentinel electronic trip unit on the front to protect
against overloads and short circuits.
It has a display and adjustment dials enabling the user to configure the protection settings and
monitor its normal operation.

- clear an alarm after the air circuit breaker
has tripped,
- navigate through the display screens.
3Dials for making adjustments to the
Sentinel electronic trip unit.
4Rated current value In of the air circuit
breaker. This value is provided by the
Rating Plug installed in the electronic trip
unit.
5USB-C port to connect a battery.
The Sentinel electronic trip unit is self-
powered when the circuit breaker is in
service except when:
- if the circuit breaker is open or de-
energised after tripping,
- if the withdrawable circuit breaker is in
test or disconnected position.
In these cases, you are advised to
connect an external battery to this USB-C
port or an external 24 VDC power supply
(Hager HTG911H) to the TU 24 V +/-
terminals of the terminal block in order to
view the settings through the display.
This USB-C port also allows connection
to a computer equipped with the Hager
Power Setup commissioning software
(see chapter 4.1 Principle)
6Backup battery powering the display after
electrical tripping.
It ensures that the alarm signals on the
display providing information of the cause
of the tripping are maintained.
7Backup battery housing hatch.

1Overload indicator: displayed as soon as the current exceeds 105% of Ir.
2Error indicator: displayed when an error is detected.
3Maintenance indicator: displayed when a maintenance intervention is required.
4Text display area: displays the name of the protection parameter during adjustment or after a trip in
addition to the error codes of detected operating system alarms.
5Low or missing battery indicator: displayed if the electronic trip unit backup battery needs
changing or is not connected.
6Tripindicator: together with the digital display zone, the text display zone and the phase display,
enables the cause of the tripping to be precisely determined.
7Overload indicator: flashes as soon as the current exceeds 105% of Ir and is lit and steady above
112.5% Ir
8Overload pre-alarm indicator: warns of an imminent tripping risk.
9ReadyToProtect indicator: displayed when the trip unit is operational and ready to protect.
ADigital display zone: used to display the values of the various settings and what the tripping value
was, using the following units.
