The opening coils, YO and YO2, and the closing coils, YC and YC2, allow the circuit-breaker
to be controlled remotely.
The opening of the circuit-breaker is always possible with the circuit-breaker closed, while
closing is possible with the circuit-breaker open and the closing springs loaded.
The opening and closing coils can operate in two different modes:
• instantaneous service (the minimum duration of the command impulse must be 100ms).
• service with permanent power supply.
NOTE: The second opening coil YO2 is alternative to the under-voltage coil YU.
IMPORTANT:
• In the case of permanent power supply, if the closing coil trips it is
necessary, after opening, to momentarily de-energize the coil in order to

be able to re-use it for the subsequent closing.
• If instead the opening coil trips, it is necessary, after having de-energized
it, to wait at least 30ms before operating the closing coil.
