“Fusible” pin
The coupling cylinder of the pole (2) is maintained to circuit--breaker in
”OPENED” position by a ”fusible” pin (1) assembled in factory. The holding
of the coupling cylinder -- in this position -- is essential to ensure the coupling
with the operating mechanism in good conditions.
NOTE
: This ”fusible” pin will be broken at the first operation.
The holding of the ”fusible” pin -- in its housing -- is ensured by a stop ring
(3) held by a screw (4).
Before continuing the installation of the pole, checking the
presence
of this stop
ring.
