VD4/L 12-17-24 (left lateral operating mechanism)
The basic cabling ends at a terminal box. The terminal box is fitted with
a removable part which allows the customer to make a disconnectable
power cord (see images at the side).
The basic version also includes the following accessories to be specified
at the time of ordering: (see Kits 1, 2, 3).
Kit 1
set of five open/closed auxiliary contacts or, alternatively and on
payment, ten or fifteen auxiliary contacts. Each shunt opening
release uses one NO auxiliary contact to de-energise after having
opened the circuit-breaker, therefore there is one NO auxiliary
contact less
Kit 2
shunt opening release.
Kit 3
key lock.
Standard fittings for fixed circuit-breakers
VD4/R fixed circuit-breakers with right lateral operating mechanism
(230 or 300 mm centre distance) and VD4/L fixed circuit-breakers with
left lateral operating mechanism (230 or 300 mm centre distance)
The basic coded version of the fixed circuit-breakers is always three-
pole and is fitted with:
1
opening pushbutton
2
closing pushbutton
3
operation counter
4
mechanical signalling device for circuit-breaker open/closed
5
lever for manual spring charging (incorporated in the operating
mechanism)
6
mechanical signalling device for closing springs charged/
discharged.
