YO-YC-YO2-YC2 : Opening

and closing coil

The opening coils, YO and YO2, and the closing coil, YC and YC2
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 charged.
The opening and closing coils can operate in two different modes:
• instantaneous service (the minimum duration of the command impulse must be 100 ms).
• service with permanent power supply.
YO-YC-YO2 for E1.2
YO-YC-YO2-YC2 for E2.2 - E4.2 - E6.2
NOTE: the second opening coil YO2 is alternative to the undervoltage coil YU.
IMPORTANT:
• If the closing coil is permanently energized and the opening coil trips, after opening,
the closing coil must be momentarily de-energized so that it can be reused for the next
closing operation.
• If instead the opening coil trips, it is necessary, after having de-energized it, to wait at
least 100 ms before operating the closing coil.
