Comprising two independent parts, line and
load side, the safety shutters automatically
block access to the main disconnects when
the circuit breaker is in the disconnected,
test or fully withdrawn position.

The rejection feature ensures that only the
properly designated circuit breaker is
matched with the selected cradle assembly.
It is made of two parts (one for the frame
and one for the stationary assembly), and
allows 20 different combinations.
