Application: For use when there is a maximum requirement for safety and continuity of service The fused GW9C bypass disconnect combination provides safe isolation of the CHZ4 while maintaining service continuity with a fuse protected circuit
Features: The cutout portion of the combination is a base mounted HX, and will accommodate both 100 A and 200 A fuseholders, The disconnect switches have 600 A continuous rating
The bypass disconnect combination consists of:
1, A fuse cutout and a single pole disconnect switch mounted in
tandem on a common base
2, A separately mounted single pole companion disconnect switch
The fuse cutout provides the bypass component of the combination The disconnect switches provide for isolation of the Vaccum circuit recloser
Operation: With the oil circuit recloser in the closed position (in preparation for maintenance):
1. Place the fuseholder in hinge clip and close the cutout into the
bypass position
2. Open the oil circuit recloser
3. When both disconnect switches are opened, the vaccum circuit recloser is isolated and bypassed
