Introduction
Switchgear with the VC-W MR2 integral racking option allows an
operator to remotely rack a VCP-W breaker or auxiliary drawer
from a distance of 30 ft . (9 .14 m) or greater depending on the
communication option installed . The integral racking assembly
consists of a controller and a motor mounted in the rear of the
breaker or auxiliary pan assembly, as well as safety and component
position sensing devices located on the racking mechanism of the
breaker and auxiliary pan assembly . The controller accepts 120 Vac
and supplies power to the motor based on user input . The position
of the VCP-W breaker or auxiliary drawer is detected by two limit
switches located on the side of the racking mechanism .
