Page 30: Section 5: Description And Operation
SECTION 5: DESCRIPTION AND OPERATION INTRODUCTION Type VCP-WL vacuum circuit breakers are horizontal drawout designs for use in metal-clad switchgear compartments. These breakers 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. -
