- Page 2 GEI-88767 BREAK SWITCH lOAD TYPE SE-100 INTRODUCTION The type SE-100 Load Break Switch is manually or electrically operated, triple pole disconnecting switch with an integral interrupter that has capability of interrupting transformer magnetizing and load currents within its rating. The SE-1003 has a manually charged, spring stored energy operating mecha nism capable of closing the switch against maximum rated short circuited current.
- Page 3 GEI-88767 the incoming side of a power transform er, the primary bus1or to cables by the use of potheads . When applied with power fuses, the combinat ion serves as a successful switching and fault protection device. Operation of the switch is accomplish ed by manual rotation of a handle The SE-lOOS switch has a positive closing and through an arc of 180°.
- Page 4 GEI-88767 The switch should be stored in a warm dry location to protect the insulation parts from condensation. The switch should be stored in a clean location free from corrosive gases or fumes. Particular care should be taken to protect the equipment from moisture and cement dust, as this combination has a very corrosive effect on many parts.
- Page 5 GEI-88767 Check all items listed under Adjustments before the switch is put in operation and during each period of maintenance. DESCRIPTION OF OPERATION SE-lOOE AND SE-lOOS On the SE-lOOE and SE-lOOS switches both the closing and opening opera tion is accomplished by the spring-charged mechanism (6) Fig. 1 located on the front of the switch assembly.
- Page 6 GEI-88 7 6 7 When the closing switch contacts are made the start-stop relay (3) Fig. will close contacts and energize the motor in the proper direc tion. At the same time a closing seal-in relay assures a complete operation without hesitation and mades the closing of the SE-lOOE switch independent of the operator.
- Page 7 GEI-88767 Remove the rear bolt from position (lA) of the spring stop (2) located on the upper right angle frame. On 1200A switches it may be necessary to loosen the front bolts of the right hand barrier to have access to the bolts. Rotate the stop until it is vertical, replace the bolt that had been removed in the lower location (1) and tighten.

- Page 9 GEI-88767 (10) Fig. 7 at the bottom of the chute. Position the chute so that the blade will travel the full length without binding or heavy scrap ing, and tighten the bolts. A dimension of 1-1/6" should be maintained from the rear edge of the arc chute to the front edge of the primary finger contact support at all times when moving or re-aligning the chute.
- Page 10 GEI-88767 with a spring scale against the contact surface. Loosen or tighten the contact bolts (7) Fig. 8 as necessary. The correct hinge pressure is essential for proper operation of the switch. The hinge pressure is difficult to measure, but a required torque to move the primary blades can be easily measured and can be substituted for a,pressure measurement.
- Page 11 GEI-88767 LUBRICATION In order to maintain reliable operation, it is important that all parts of the mechanism be properly lubricated at all times. All bearings and other parts of the mechanism subjected to wear have been properly lu bricated, during assembly at the factory, using the finest grades of lubricants available.
- Page 12 GEI- 88767 able to leave the bearings in the alcohol for a lo�er time, an in hibited alcohol such as is used for anit- freeze should be used. Even then the bearings should be removed from the alcohol within twenty four hours.
- Page 13 GEI-88767 ADJUSTMENTS SE-lOOM Mechanism Stop Refer to Page 6. Primary Wipe When the switch is in the closed position, there should be no clearance between the primary blades and the primary finger support. The length of the operating rod should be adjusted so that there is noticeable force involved when the operating rod goes over center near the end of the closing stroke.
- Page 14 GEI-88767 The SE-lOOM hook release should be adjusted to release the auxiliary blade when the primary contacts and blade are 1/2" 1" apart. Be certain the auxiliary blade latches into the arcing contacts in the chute on each operation. The auxiliary blade is released before the primary c0ntacts are closed so that it will close first and give a positive closing action even when the switch is inadvertantly op...

The high potential test is also recommended for devices which have been removed from service and stored over an extended period of time under unfavorable atmospheric conditions.
