3.2.7 Forced tripping release (Code 13)
•
Optionally, the forced tripping release (FT) can be installed
in the breaker [Fig. 6]. This mechanical trip releases the
breaker, by pressing the pin located in the bottom plate.
Force required to trip the breaker is about 110 N (~25 ft-
lb). The tripping pin position is shown on Fig. 6.
•
WARNING: This device, when active, does not prevent
breaker from closing. Closing the breaker against
activated FT may lead to damage of this release.
•
With a correctly designed interlock in an enclosure, FT
provides safety-tripping function. During withdrawal
operation of the trolley, the breaker is tripped BEFORE its
main terminals disconnect from the bus.

3.2.8 Lever for manual operating (Code 16)
•
Optionally, a hand lever for manual closing and opening
operation during maintenance is available. This tool must
not be use while breaker is energized!
•
To close the contacts, install hand lever (1) on the drive’s
rod, and pull it out smoothly until latches snap [Fig. 7].
Safe manual closing is shown on the Fig. 26, chapter 6.1.2.
•
To open the contacts, insert lever’s pin (3) into the ring (2)
and push it hard until breaker opens [Fig. 8] and [Fig 27].
•
WARNING: Manual closing and opening – only during
maintenance!
•
Alternative manual closing and opening operation is
possible by rotating the main shaft of the breaker
mechanism, which is accessible from both side. Use
10 mm hexagon-box wrenches to OPEN/CLOSE [Fig. 9]. To
close the breaker, shafts from both sides have to be
rotated simultaneously.
•
WARNING: Pay attention to control rotation speed of the
shaft during manual opening and closing. Impede the
wrench to avoid hitting it to the ground, which may lead
to a hand injury.
