Geared motor for the automatic charging ofthe closing springs3) Geared motor for the automatic chargingof the closing springs (M)This automatically charges the closing springs of the circuitbreakeroperating mechanism. After circuit-breaker closing,the geared motor immediately recharges the closing springs.The closing springs can, however, be charged manually (usingthe relative operating mechanism lever) in the event of a powersupply failure or during maintenance work.It is always supplied with a limit contact and microswitch forsignalling that the closing springs are charged (see accessory5d).1SDC200139F0001Reference figure in electrical circuit diagrams: M (1)5CharacteristicsPower supplyOperating limits:Inrush power (Ps):Rated power (Pn):Inrush timeCharging time:Insulation voltage:24-30 V AC/DC48-60 V AC/DC100-130 V AC/DC220-250 V AC/DC85%...110% Un (CEI EN 60947-2 Standards)DC = 500 WAC = 500 VADC = 200 WAC = 200 VA0.2 s4-5 s2500 V 50 Hz (for 1 min)1SDC200140F00015/10ABB SACE
