CUTLER-HAMMER 24kV Type W-VAC Circuit Breaker

STORAGE

If the circuit breaker is to be placed in storage,

maximum protection can be obtained by keeping

it packed as shipped. Before placing it in

storage, checks should be made to make sure

that the circuit breaker is free from shipping

damage and is in satisfactory operating

condition.

The circuit breaker is shipped with its contacts

open and closing springs discharged. The

indicators on the front panel should confirm this.

Insert the maintenance tool in the manual

charge socket opening Figure 3-5 and 4-1.

Charge the closing springs by pumping the

handle up and down approximately 38 times

until a crisp metallic "click" is heard. This

indicates that the closing springs are charged

and is shown by the closing spring "charged"

(yellow) indicator. Remove the maintenance

tool. Push the "manual close" button (green).

The circuit breaker will close as shown by the

circuit breaker contacts "closed" (white)

indicator. Push the "manual trip" button (red).

The circuit breaker will trip as shown by the

circuit breaker contacts "open" (black) indicator.

After completing this initial check, leave the

closing springs "discharged" and circuit breaker

contacts "open".

Outdoor storage is NOT recommended. If

unavoidable, the outdoor location must be well

drained and a temporary shelter from the sun,

rain, snow, corrosive fumes, dirt, falling objects

and excessive moisture must be provided.

Container should be arranged to permit free

circulation of air on all sides and temporary

heaters should be used to minimize

condensation. Moisture can cause rusting of

metal parts and deterioration of high voltage

insulation. A heat level of approximately 400

watts for each 4 cubic meters of volume is

recommended with the heaters distributed

uniformly throughout the structure near the floor.

Indoor storage should be in a building with

sufficient heat and air circulation to prevent

condensation. If the building is not heated, the

same general rule for heat as for outdoor

storage should be applied.

Effective 12/98
