Mis-insertion preventor
For drawout type
When moving the breaker from the connected position to the test positions,
this contact is used to short-circuit the auxiliary switch (LAXb), thus maintaining the
correct sequence of operation of the external control circuit. When ordering, SBC with
the same number of contacts as auxiliary switches (LAXb) will be provided. Up to 5
SBCs can be mounted.
