3.2. eleCtrICAl operAtIon

The operation of the circuit breaker by electrical control is executed by means of
the motorized drive and by the closing and opening coils, accessories installed
internally in the circuit breaker.
The motorized drive loads the springs of the operation mechanism automatically,
whenever the circuit breaker is turned off, an operation which ends after approximately
5s. The power supply of the motor is executed by the terminals U1 and U2.
In order to turn on the circuit breaker, when its springs are loaded, a voltage pulse
is applied to the terminals of the closing coil (A1 and A2).
In order to turn off the circuit breaker, a voltage pulse is applied to the terminals of
the opening coil (C1 and C2). In circuit breakers equipped with a subvoltage coil, the
circuit breaker can be turned off cutting the power supply of this coil (D1 and D2).
