5.3. Fuse protection function with AR driving mechanism
5.3.1. Mimic diagram
The AR driving mechanism has a stored energy operating
system. The opening operation uses the energy stored
during the closing operation, whether manual or motorised.
This energy is retained by means of a latch device. It can
then be released during the opening operation by manually
driving this latch device. The operation speed and strength
are independent of the action of the operator.
