NOT FOLLOWING THE PROCEDURE CAN FAIL TO UNCOVER SHIPPING DAMAGE THAT MAY RESULT IN INCORRECT CIRCUIT BREAKER OPERATION LEADING TO DEATH, BODILY INJURY, AND EQUIPMENT DAM-AGE.
3A74374H04 Page 28 4-8 ELECTRICAL OPERATION CHECK After having completed all previous checks and tests, the circuit breaker is ready to be operated electrically. It is preferred that this check be made with the circuit breaker in a TEST position or by using a test cable, if the circuit breaker is outside the cell structure. CAUTION BEFORE INSERTING THE CIRCUIT BREAKER EXAMINE THE INSIDE OF THE CELL STRUCTURE FOR EXCESSIVE DIRT OR ANYTHING THAT MIGHT INTERFERE WITH THE CIRCUIT BREAKER MOVEMENT.

3A74374H04 Page 30 To remove the circuit breaker from the structure, reverse the procedure just described by turning the levering-in crank in a counterclockwise direction. Keep in mind that safety interlocks may cause the circuit breaker to open and/or springs to discharge during the removal process. It depends on what condition the circuit breaker was in as removal began. For additional information on the levering mechanism, refer to paragraph 5-6 in this manual. 4-8.
3A74374H04 4-9 Page 31 CIRCUIT BREAKER/STRUCTURE INTERFACING WARNING NEVER DISABLE OR DEFEAT ANY INTERLOCKS. THEY ARE INTENDED FOR PROPER AND SAFE OPERATION. FAILURE TO COMPLY COULD RESULT IN DEATH, SEVERE PERSONAL INJURY AND/OR PROPERTY DAMAGE DUE TO THE HAZARDOUS VOLTAGE PRESENT. Type VCP-W Circuit Breakers are supplied with a series of interlocks to insure safe and proper interfacing between the circuit breaker and its compartment.
3A74374H04 Positive Interlock The positive interlock prevents the levering-in crank from being engaged if the circuit breaker is closed in the CONNECTED position. Negative Interlock The negative interlock prevents the circuit breaker from closing between the CONNECTED and TEST positions. Position Closing Interlock The circuit breaker is prevented from closing automatically when it is moved from the TEST to the CON NECTED position if the closing switch is maintained during the levering-in operation.
3A74374H04 Page 33 SECTION 5: DESCRIPTION AND OPERATION 5-1 INTRODUCTION Type VCP-W, VCPW-SE and VCPW-ND vacuum circuit breakers are horizontal drawout designs for use in metalclad switchgear compartments. Most ratings can be stacked two high in a vertical section resulting in a considerable savings of floor space. Vacuum interrupters are used with all circuit breakers to close and open the primary circuit.
3A74374H04 Page 34 are maintaining the adequate contact pressure to keep the contacts closed. Severe contact erosion would result in an unacceptable indication from the indicator (Figure 6-4). Depending upon the structural design, a small mirror may be required to inspect all three poles. Note that the actual configuration and/or appearance of the indicator can vary from one circuit breaker rating to another.

In addition, refer to the instruction manual supplied with the switchgear assembly. Page 44 5-7 All circuit breakers are equipped with a mechanical operations counter. As the circuit breaker opens, the linkage connected to the pole shaft lever advances the counter reading by one (Figure 3-3).
3A74374H04 Page 45 SECTION 6: INSPECTION, MAINTENANCE AND TROUBLESHOOTING element annually or every 500 operations, which ever comes first. b. For special conditions such as frequent circuit breaker element operation, contaminated environments, and high temperature/humidity conditions, the inspection frequency should be a minimum of twice per year. 6-1 INTRODUCTION WARNING DO NOT WORK ON A BREAKER ELEMENT WITH PRIMARY POWER APPLIED.
3A74374H04 Page 46 considered to be qualified. Refer to further definitions in the National Electrical Safety Code. For the purpose of inspecting and maintaining such equipment, a qualified person must also be trained in regard to the hazards inherent to working with electricity and the proper way to perform such work. Such an individual should be able to de-energize, clear and tag circuits in accordance with established safety practices.

3A74374H04 Page 48 6-4 VACUUM INTERRUPTER INTEGRITY TEST Vacuum interrupters used in Type VCP-W Vacuum Circuit Breaker Elements are highly reliable interrupting elements. Satisfactory performance of these devices is dependent upon the integrity of the vacuum in the interrupter and the internal dielectric strength. Both of these parameters can be readily checked by a one minute ac high potential test. Refer to Table 6.2 (page 31) for the appropriate test voltage.
3A74374H04 Page 49 Figure 6-2 Vacuum Interrupter Showing Contact Erosion Indicator with Breaker Open (Shown Here for Clarity Purposes Only) CAUTION SOME DC HIGH POTENTIAL UNITS, OPERATING AS UNFILTERED HALF-WAVE RECTIFIERS, ARE NOT SUITABLE FOR USE TO TEST VACUUM INTERRUPTERS BECAUSE THE PEAK VOLTAGE APPEARING ACROSS THE INTERRUPTERS CAN BE SUBSTANTIALLY GREATER THAN THE VALUE READ ON THE METER.

If a solvent is required to cut dirt, use Stoddard’s Solvent Eaton 55812CA or commercial equivalent. Secondary control wiring also requires inspection for insulation damage. 6-7 INSULATION INTEGRITY CHECK Primary Circuit: The integrity of primary insulation may be checked by the 60Hz AC high potential test.
3A74374H04 Page 51 the voltage for one minute. Successful withstand indicates satisfactory insulation strength of the secondary control circuit. Remove the shooting wire and reconnect motor leads. 6-8 PRIMARY CIRCUIT RESISTANCE CHECK Since the main contacts are inside the vacuum chamber, they remain clean and require no maintenance at any time. Unlike many typical circuit breaker designs, VCP-W breakers do not have sliding contacts at the moving stem either.
3A74374H04 Page 52 CAN RESULT FROM CONTACT WITH ENERGIZED EQUIPMENT. ALWAYS VERIFY THAT NO VOLTAGE IS PRESENT BEFORE PROCEEDING WITH THE TASK, AND ALWAYS FOLLOW GENERALLY ACCEPTED SAFETY PROCEDURES. Safety Precautions: Read and understand these instructions before attempting any maintenance, repair or testing on the breaker. The user is cautioned to observe all recommendations, warnings and cautions relating to the safety of personnel and equipment.
