Characteristics Of The Electrical Accessories - ABB VD4 36 Installation And Service Instructions Manual

5.5.4. Standard fittings for withdrawable circuit-breakers
The basic versions of the withdrawable circuit-breakers are
three-pole and provided with:
– EL type manual operating mechanism
– Mechanical signalling device for closing spring charged/dis -
charged
– 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 set of ten auxiliary contacts supplied as standard and
the maximum electrical accessories, three break contacts are available
(signalling circuit-breaker open) and four make contacts (signalling circuit-
breaker closed).
– Lever for manual charging of the closing spring incorporated
in the operating mechanism
– Isolating contacts
– Racking-out/racking-in lever (the quantity must be
established according to the number of pieces of apparatus
ordered).
