Spring charge indicator.10. The close bar and trip plate.11. Steel front cover.12. Nameplate with complete rating information.The Type DSL-206 and DSL-416 drawout elements alsoinclude the following components:1. Current limiters.2. Isolating transformers, connected in parallel with thelimiters.3. Combination “Blown Limiter Indicator” and anti-singlephase device, connected to the isolating transform-ers, actuated by blowing of one or more of the currentlimiters. This device has individual phase indicatorsand a common “RESET” button extending throughthe front cover.Each breaker is equipped with a spring-type storedenergy closing mechanism. This mechanism closes thecircuit breaker contacts with the necessary speed andforce, independently of the operator. Basically, the clos-ing springs must first be charged or cocked before thebreaker can be closed. The springs are then released byreleasing the spring release latch. The breaker is openedby releasing the tripping latch.3.1 INDEPENDENT MANUAL AND POWER-OPERATED BREAKERS3.1.1 Closing FacilitiesOn manually operated breakers, the closing springs canbe charged only by hand, by means of the spring-chargehandle. The actual closing of the breaker is done only byhand-push on the close bar. As optional equipment, theelectrical spring release attachment normally suppliedonly on power-operated breakers can be supplied onmanually operated breakers.On power-operated breakers, the springs are normallycharged by an electric motor. Closing may be done elec-trically by an electro-magnet which lifts the closing springrelease latch. Both of these operations can be done byhand if the control power source fails.3.1.2 Tripping FacilitiesThe breaker can be tripped open by hand by pushing withthe finger on the trip plate on the breaker panel or the tripplate on the breaker compartment door (the latter is oper-ative only when the breaker is in the connected position).The breaker can also be tripped electrically by the follow-ing devices:1. Shunt trip device, optional equipment on manuallyoperated breakers.2. Trip Actuator, energized from the Amptector trip unit.3. Undervoltage Trip Device (Optional on all breakers).4. Blown Limiter Indicator (for DSL breakers).3.2 LEVERING DEVICEThe drawout element has four normal positions in itscompartment, determined by the levering device:1. The REMOVE position, Figure 6.2. The DISCONNECT position.3. The TEST position, Figure 7.4. The CONNECT position, Figure 8.The REMOVE position is the first position in the compart-ment as the element is pushed directly by hand as far asit will go. The DISCONNECT, TEST, and the CONNECTpositions are reached only by means of the leveringdevice. This is hand operated with a removable crankhandle. This handle is placed on the levering deviceworm shaft, which is exposed by depressing the shutter.
