FAILURE TO DO SOCOULD CAUSE PERMANENT EQUIPMENT DAMAGE.1-2 GENERAL INFORMATIONThe purpose of this book is to provide instructions forunpacking, storage, use, operation and maintenance ofType VCP-W, VCPW-SE, and VCPW-ND Vacuum CircuitBreakers. These circuit breakers are horizontal drawouttype removable interrupting elements designed for usein VacClad-W Metal-Clad Switchgear and appropriateVCP-W modules. They provide reliable control and pro-tection for medium voltage electrical equipment and cir-cuits. All VCP-W circuit breaker elements are designedto ANSI Standards for reliable performance, ease ofhandling and simplified maintenance. In addition, VCP-W circuit breakers are tested to both ANSI and IECStandards for application around the world.The VCPW-SE circuit breaker element is a VCP-W cir-cuit breaker designed specifically for special environ-ment applications and operating conditions through 27kV. The VCPW-ND circuit breaker element is a narrowdesign VCP-W circuit breaker designed specifically foruse in 5 kV applications where floor space requirementswould not allow the industry standard 36 inch wideswitchgear. From this point on, all circuit breaker ele-ments will be referred to as Type VCP-W unless the ref-erence is specific to a particular design.SATISFACTORY PERFORMANCE OF THESE CIRCUITBREAKER ELEMENTS IS CONTINGENT UPON PROP-ER APPLICATION, CORRECT INSTALLATION ANDADEQUATE MAINTENANCE.
