5.3.2. Standard fittings for fixed circuit breakers
The basic versions of the fixed 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: application of the shunt opening release and/or additional shunt
opening release foresees the use of one or two auxiliary make contacts
(normally open), thereby reducing the number of auxiliary contacts available.
• lever for manual closing spring charging
• auxiliary circuit support terminal box.
