Descrpton A MVS Pow-R-Drve motor operated swtch s a standard, manuallyoperated swtch n combnaton wth a heavy-duty electrc motor-drven lnear actuator whch charges the sprng. The lnear actuator s located n a separate solated low voltage compartment. Durng electrcal operaton, t smoothly and quetly extends or retracts the proper dstance to cause the swtch mechansm to operate. Standard motor operators are mounted n the swtch enclosure. Ths elmnates the separate motor compartment conservng floor space. Manual Operaton A steel clevs pn connects the lnear actuator to the sprng chargng mechansm. Ths pn can be removed by hand and the lnear actuator pvoted away from the mechansm allowng manual operaton. Key Interlock to Lock Swtch Open A keyed lock s standard to lock the swtch n the open poston only. Ths lock not only locks the swtch n the open poston, but also breaks the electrcal motor contacts ntegral to the lock and permts the key to be removed. Wth the key, the operator can then open the lock on the swtch door. Ths scheme gves postve assurance that the swtch s open and cannot be closed wth the door open.

See Secton for further nformaton on these devces. MVS swtchgear assembles can also be equpped to nterface wth the Cutler-Hammer PowerNet ntegrated montorng and control communcatons system wth Communcaton (PONI) accessores, Addressable Relays, etc. See Secton for further nformaton. Other Meters: IQ 0 IQ 00 Refer to Secton. Outdoor Enclosures Weatherproofng complyng wth the requrements of NEMA R and IEEE standard C.. s avalable for MVS swtchgear assembles. The weatherproofng conssts of sloped roof panels that are joned together wth caps. Doors and rear covers are fully gasketed. Externally accessble louvered fltered covers, top and bottom, front and rear, are provded for ventlaton. At least one 0 watt heater s provded n each vertcal secton. Power for the heaters may be suppled from an external source, or an optonal ntegral control power transformer may be specfed to provde power for the heaters.

3 .0- Metal-Enclosed Swtchgear MVS Medum Voltage Load Interrupter Fusble Swtch Techncal Data June 0 Sheet 0 Techncal Data Test Data All Eaton s Cutler-Hammer MVS swtch ratngs have been thoroughly tested n recognzed hgh power laboratores wth certfed nspectors from both UL and CSA organzatons. Tests were performed to substantate all publshed ratngs n accordance wth ANSI, IEEE, CSA and NEMA standards. The testng program ncluded tests of: Basc mpulse levels. Momentary wthstand. Short tme wthstand. Fault closng. Load nterruptng at varous loads, varous power factors. Mechancal lfe tests. Temperature rse test. These tests verfed not only the performance of the swtch and ntegrated swtch-fuse assembly, but also the sutablty of the enclosure ventng, rgdty and bus spacng. The mechancal lfe test subjected the MVS swtch to a number of no load cycles greater than the requrements tabulated n ANSI C. standards. There were no movng or current carryng part falures as a result. The Fault Close and Load Interruptng test demonstrated sgnfcant mproved performance above ANSI/ IEEE standards.
