50/75VCPW-VSR

Breaker To Vacuum Starter Replacement Unit

EATON CORPORATION www.eaton.com

SECTION 3: RECEIVING, HANDLING, AND 
STORAGE

Type VCP-W VSR-series breaker to vacuum starter replacement units 

are subjected to complete factory production tests and inspection 

before being packed. They are shipped in packages designed to 

provide maximum protection to the equipment during shipment 

and storage and at the same time to provide convenient handling. 

Accessories such as the cell code plate, etc. are shipped with the 

unit (Figure 3.1).

3.1  RECEIVING

Until the unit is ready to be delivered to the switchgear site for 

installation, DO NOT remove it from the shipping crate. If the unit 

is to be placed in storage, maximum protection can be obtained by 

keeping it in its crate.
Upon receipt of the equipment, inspect the crates for any signs of 

damage or rough handling. Open the crates carefully to avoid any 

damage to the contents. Use a nail puller rather than a crow bar 

when required.
When opening the crates, be careful that any loose items or 

hardware are not discarded with the packing material. Check the 

contents of each package against the packing list.
Examine the unit for any signs of shipping damage such as broken, 

missing or loose hardware, damaged or deformed insulation and 

other components. File claims immediately with the carrier if 

damaged or loss is detected and notify the nearest Eaton’s Electrical 

Services & Systems office.

Tools and Accessories

CNnoaco Wtar  Gaugte: 

Optional item used to check contact wear. 

(Style 5259C11H01) (See Section 5)

Racking Handlte:

 The original VCP-W racking handle is used to assist 

in moving the MV-VSR into and out of the cell.

Lifoing YNkte: 

Optional lifting device that can be used to install a VSR 

into upper compartment of VCP-W switchgear. (Style 94M7103G99)

3.2  HANDLING

 WARNING

DO NOT USE ANY LIFTING DEVICE AS A PLATFORM FOR PERFORMING 

MAINTENANCE, REPAIR OR ADJUSTMENT OF THE UNIT OR FOR OPENING, 

CLOSING THE CONTACTS OR CHARGING THE SPRINGS. THE UNIT MAY 

SLIP OR FALL CAUSING SEVERE PERSONAL INJURY. ALWAYS PERFORM 

MAINTENANCE, REPAIR AND ADJUSTMENTS ON A WORKBENCH 

CAPABLE OF SUPPORTING THE UNIT. 

VCPW-VSR unit shipping containers are designed to be handled 

either by use of a rope sling and overhead lifting device or by a 

fork lift truck. If containers must be skidded for any distance, it is 

preferable to use roller conveyors or individual pipe rollers.

Once the unit has been inspected for shipping damage, it is best to 

return it to its original shipping crate until it is ready to be installed in 

the Metal-Clad Switchgear.

When the unit is ready for installation, a lifting harness in conjunction 

with an overhead lift or portable floor lift can be used to move the 

unit, if this is preferable to rolling the unit on the floor using self 

contained wheels. If the unit is to be lifted, position the lifting device 

(lifting straps should have at least a 1600 pound capacity) over the 

unit and insert the lifting harness hooks into the unit side openings 

and secure. Be sure the hooks are firmly attached before lifting 

the unit. Stand a safe distance away from the unit while lifting and 

moving.
