Shipping and Handling

Inspection

Examine the shipment for external evidence of damage as 
soon after receipt as possible, preferably before removal 
from the carrier’s conveyance. Check the bill of lading to 
make sure the shipping skids, crates, and containers listed 
are present. If there is visible loss or damage:
1.  Notify the delivering carrier immediately.
2.  Ask for a carrier inspection.
3.  Note the condition of shipment on all copies of the 

delivery receipt.

4.  File a claim with the carrier.

If concealed damage is discovered:

1.  Notify the delivering carrier within 15 days of receipt of 

shipment.

2.  Ask for a carrier inspection.
3.  File a claim with the carrier.

Also, notify S&C Electric Company in all instances of 

loss or damage.

Handling

NOTICE

DO NOT DROP the VacuFuse Self-Resetting 
Interrupter or subject any of its parts to undue stress 
during installation . Only remove a VacuFuse Self-
Resetting Interrupter from the carton immediately 
before installation .

Storage

VacuFuse Self-Resetting Interrupters are shipped on 
pallets banded with plastic wrap. This packaging is 
designed to protect the VacuFuse interrupters from freight 
damage. This packaging is not suitable for outdoor storage 
as it can pool water and damage VacuFuse interrupters. 
After receipt, VacuFuse interrupters should be stored 
indoors in their shipping packaging. Storing VacuFuse 
interrupters outdoors in the shipping packaging will void 
the warranty.

Returning 

When returning the VacuFuse Self-Resetting Interrupter 
for any reason, place the VacuFuse interrupter in the 
original shipping carton to prevent damage during 
shipment. If additional shipping cartons are required, 
contact the nearest S&C Sales Office, S&C Authorized 
Distributor, or S&C Headquarters.
