Undervoltage release coil UV
or Shunt trip coil SH
The SH shunt trip coils and CC closing coils can be controlled by the sentinel Energy trip unit
using the INS insulation module (See Chapter 17.14 Installation of the communication and
display accessories).
MO charging Motor
The MO charging motor is
positioned on the right side

Coils
Three types of coils can be installed in the dedicated positions behind the front cover of the
circuit breaker:
ATTENTION
Connection of the coils for a sentinel Energy trip unit.
The length of the connection cables between:
- the terminals A1/A2 and A3 of the CC closing coils,
- the terminals Cx1/Cx2 and Cx3 of the SH shunt trip coils,
is limited to 5 m for the 200-250 V coils (beyond that, an intermediate relay is necessary).
A bridging must be performed between the closest terminal between A2 and A3 and/or
Cx2 and Cx3 (less than 10 cm) in order to be able to use a shunt trip coil and/or CC closing
coil of 380-480 V AC.
Remote control (via Modbus or Bluetooth) is therefore not possible with 380-480 V AC
coils.
