W = Width of the switchgear.
P = Pole horizontal centre distance.
u/l = Distance between bottom and top terminal.
ø = Diameter of the isolating contact.
5.5.3. Standard fittings for withdrawable circuit-breakers for UniGear ZS1 switchgear
The basic versions of the withdrawable circuit-breakers are 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 set of ten auxiliary contacts supplied as standard and the maximum number
of electrical applications possible, 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 (plug only) 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 the circuit-breaker from being racked into
the panel with auxiliary circuits not connected (plug not inserted in the socket).
