5.4.3. Standard fittings for withdrawable circuit-breakers for
UniGear type 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 springs charged/discharged
– mechanical signalling device for circuit-breaker open/closed
– closing pushbutton
– opening pushbutton
– operation counter
– set of ten circuit-breaker open/closed auxiliary contacts.
Note
With the group of ten auxiliary contacts, as standard, and the maximum of the
requested applications, the following are available: three opening contacts
(signalling circuit-breaker open) and five closing contacts (signalling circuit-
breaker closed).
– lever for manually charging the closing springs
– 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. It prevents racking-in of the circuit-
breaker in the panel with auxiliary circuits not connected (plug not in-
serted in the socket).
