Construction characteristicsOperating mechanismThe operating mechanism is of the stored energy type, operatedusing pre-charged springs.The springs are charged manually by operating the front leveror using a geared motor, supplied on request.The opening springs are charged automatically during the closingoperation.With the operating mechanism fitted with shunt closing andopening releases and the geared motor for charging the springs,the circuit-breaker can be operated by remote control and, ifrequired, co-ordinated by a supervision and control system.1➁ OPENING➀ CLOSING➀ OPENING➂ OPENING➁ CLOSING1SDC200020F00011SDC200021F0001The following operating cycles are possible without rechargingthe springs:– starting with the circuit-breaker open (0) and the springscharged:closing-opening– starting with the circuit-breaker closed (I) and the springscharged:opening-closing-opening.The same operating mechanism is used for the entire seriesand is fitted with a mechanical and electrical anti-pumpingdevice.ABB SACE 1/5
