5.4.2. Standard fittings for withdrawable circuit
breakers for UniGear ZS1 type switchgear
550 mm wide, for PowerCube modules
600 mm wide and for UniSec 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 and opening pushbutton
• operation counter
• set of ten auxiliary circuit breaker open/closed
contacts
• lever for manually charging the closing springs
• isolating contacts
• cord with connector (plug only) for auxiliary
circuits, with striker pin on request, 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 (1).
(1) On request. This prevents racking-in of the circuit breaker in the panel
with auxiliary circuits not connected (plug not inserted in the socket).
