5.5.6. Standard fittings for withdrawable circuit-breakers for PowerCube modules
The basic versions of the withdrawable circuit-breakers are always three-pole and fitted with:
– EL type manual operating mechanism
– mechanical signalling device for closing spring charged/discharged
– mechanical signalling device for circuit-breaker open/closed
– closing pushbutton
– opening pushbutton
– operation counter
– set of ten auxiliary circuit-breaker open/closed contacts
Note: with the group of ten auxiliary contacts supplied as standard and the maximum number
of electrical applications, three make contacts (signalling circuit-breaker open) and four
break contacts (signalling circuit-breaker closed) are available.
– lever for manually charging the closing spring
– isolating contacts
– cord with connector (only plug) for auxiliary circuits, with striker pin which does not allow
connection of the plug in the socket if the rated current of the circuit-breaker is different from
the rated current of the panel
– racking-in/out lever (the quantity must be defined according to the number of pieces of
apparatus ordered)
– locking electromagnet in the truck. This prevents racking-in of the circuit-breaker in the panel
with auxiliary circuits not connected (plug not inserted in the socket).
