8.4. Standard fittings

The basic versions of the withdrawable circuit-breakers are three-pole and fitted with:
– closing pushbutton (integrated in the control panel -PI1)
– opening pushbutton (integrated in the control panel -PI1)
– mechanical operation counter
– mechanical signalling device for circuit-breaker open/closed
– manual emergency opening device
– lever for manual emergency opening (the quantity must be defined according to the number of
pieces of apparatus ordered)
– "READY" for operation signal, together with a further 11 luminous diagnostic signals on the local
interface of the circuit-breaker
– one or more capacitors for energy storage for the operation
– mobile connector for direct connection to the sockets of the electronic module, for cabling the
auxiliary circuits
– basic version control module with protections I> - I>> - I0> - I0>> (51-50-51N-50N)
– software for configuration of the protections, control, communication (if provided) and display of
the states
– Transmitted contacts in the truck (-BT1; -BT2).
Basic version control module
The control module has 16 digital inputs and 16 digital outputs which can mostly be programmed
freely, in accordance with the plant requirements by means of the configuration software.
To assign all the application meanings of the circuit-breaker, please refer to the 1VCD400060 sche-
matic drawings.
Among the fixed inputs which cannot be programmed are:
– input for the undervoltage function
– remote opening and closing commands
– disabling the opening operation
– circuit-breaker in service
– circuit-breaker under test.
– hardware only second opening of the circuit-breaker for maximum reliability.
Among the fixed outputs which cannot be programmed are:
– circuit-breaker closed and open
– unit ready signal for –RL2 (locking magnetic on the truck)
– monitoring signal.
All the remaining inputs and outputs are mapped according to established meanings if one of the
four default application diagrams is selected (withdrawable circuit-breaker, withdrawable with earth-
ing switch, fixed, fixed with earthing switch) by means of the software configurator, whereas by
ticking the 'free' diagram, it is possible to assign all the meanings available to the digitial inputs/
outputs (see Input / Output Mapping chapter).
For example:
– earthing switch position, open and closed
– functional interlocks
– local – remote control enabling keys
– resetting trip of protections
– local circuit-breaker closing and opening command
And for the outputs:
– circuit-breaker in service or under test
– protection tripped
– functional interlocks
– protections under timing (start)
– circuit-breaker opened by opening protection commands (transient contact closed for 100 ms)
