3.5 Circuit-breaker plug connector coding
The control wiring plug connector coding allows
the withdrawable parts for switching devices
to be assigned to particular panels. This ensures
that withdrawable parts with different rated
currents or different control wiring circuits can
only be used in the panels they are intended for.
Coding pins are fitted in the control wiring sockets
10.1 or control wiring plugs 10.2, and engage with
the corresponding bores of the relevant plug 10.2
or socket when the two parts are connected.
The plug connector coding is order-related, and
is noted in the relevant wiring documentation.

Coding:
(...) The corresponding coding designation for
the control wiring plug is given in brackets.
The coding pins can be fitted in the control wiring
socket and/or in the control wiring plug.
– Basic design
The number of sockets is optional but the basic
assignment is 1, 8, 10, 20, 21, 31, 33 and 40.
Sockets and pins can be mixed as required in the
control wiring socket and control wiring plug.

It is additional safety feature on the top of each
unit. The microswitch generates an immediate
fault signal when the overpressure flap is opened.
Reaction time is less then 15 ms. The signal from
the microswitch can be sent directly to trigger
the circuit-breaker OFF.
