The sentinel Energy electronic trip unit includes:
• A graphical colour display and a keyboard with six keys allowing interaction with the trip unit,
• A ReadyToProtect indicator that displays when the trip unit is operational and ready to
protect.
ATTENTION
The electronic trip unit must be powered in order for it to perform its protection functions. It is powered on condition that a minimum current
of 120 A on one phase or 80 A per phase passes through the circuit breaker.
Nevertheless, it is strongly recommended that a 24V DC SELV external power supply be connected (recommended product reference
Hager HTG911H) on the TU terminal to guarantee optimal operation of the trip unit and prevent malfunctions in the electrical installation
associated with a breach in the trip unit's continuity of operation.
