2.2 Intended use
The TracFeed
®
SFA remote motor drive (referred to in the fol-
lowing as TracFeed
®
SFA) is used to activate the switch discon-
nectors and earthing switches installed on the pole tips for inter-
city and mass transit overhead contact systems. Power
transmission takes place mechanically via an adjusting lever on
the back of the TracFeed
®
SFA, which is connected to the circuit
breaker or earthing switch by a force-displacement transmission
device.
The TracFeed
®
SFA is operated and monitored electronically
from a remote location. In the event of a fault, the TracFeed
®
SFA
can be operated manually using a crank handle.
The TracFeed
®
SFA has been designed and constructed solely for
the intended use described here.
