INTRODUCTION This instruction manual contains installation, operation and maintenance information for Types FCV-500 and F CV-750 vacuum circuit breakers of the 13.8 kV class, with Type 515-2V stored energy operators ( Fig. 2a & 2b). WARRANTY The sales contract carries all information on warranty coverage. - Page 5 Wipe the outside of the interrupters and supporting insulating parts with a clean, dry cloth. 1" & & Observe the distance "A "A2" in figure 3. An average between "A 1" "A2" will produce distance "A" which represents the additional compression imparted to the contact pressure springs from the point where the interrupter contacts make, to the point where the closing link...
- Page 6 See Fig. #19. De-energize control power and remove plug jumper. Coat movable primary and secondary disconnects with a film of Siemens-Allis contact lubricant, 15-171-370-002. Insert breaker into its c ubicle to "disconnect" position and close manually(*). Complete movement of breaker to "test" position and repeat steps 9 ( # ) and Check for proper alignment between stationary and movable secondary contacts.

Page 7: Circuit Breaker Description
C IRCUIT BREAKER DESCRIPTION A typical circuit breaker consists of primary disconnects, vacuum interrupters, and operator sections (see Page 1 8). The primary d isconnect section contains the main contacts which supply power to the load. The vacuum interrupters open and close the electrical system during normal and/or fault conditions. The oper ator section contains the mechanism used to close and open the main contacts. -

The non-contacting magnetically operated Hall effect switch and magnet actuator combine to perform proximity detection of the trip latch tail. The speed of operation and life expectancy of this proxim ity sensor system is not limited by mechanical actuation as no physical contact between the actuating magnet and Hall switch exist. -
Page 10: Reclosing Control
See Fig. 5 for sequence of operation. RECLOSING CONTROL (Optional -For Reclosing Applications Only) The electronic solid state time delay module works in concert with the trip latch check system. The time delay module consists of an electronic timer and an electro-magnetic relay. The elementary diagram, Fig. -

(16, The close latch check switch Fig. consists of a snap-action type switch mounted in close proximity to the close latch. A striker plate at the tail of the close latch engages the switch's actuator slightly before the fully reset position is achieved and actuates the svv i tch prior to the latches reaching the fully reset position. -

Functional electrical test on breaker may be made to confirm sensors operation. The timing modules nameplate and rated voltage should be checked to insure it matches breaker closing control voltage. The timers delay adjustment has been previously set and should not be altered. Removed wire from terminal 2 timer module and insulate. -

for loose connections and frayed or damaged insulation. The "close latch check switch", "trip latch check switch" (if possible), and "mechanical interlock" switch should be checked for mounting tightness. The satisfactory operation of each switch element should be assured with a continuity meter and manual manipulation of the switching element, and adj usted if necessary. -
