2.0 INTRODUCTION
These instructions do not attempt to provide the user of this equipment with every possible diffi-
culty that may occur in the application, operation and maintenance of the product. Also, as
improvement in parts and assemblies are made, some parts may differ in appearance as depict-
ed in the illustrations; however, functionality will be equivalent.
The Type R-MAG vacuum breaker is a high-voltage, three-phase device incorporating three vac-
uum interrupters, gang operated by a magnetic actuator. Together with the optional relaying and
current transformers, the breaker will sense an overload and automatically open.
Satisfactory performance of the breaker is contingent upon the correct installation, and adequate
maintenance and service of the product. Careful study of these instructions will permit the user to
obtain maximum benefit from this device.
3.0 RECEIVING, HANDLING AND STORAGE
Each breaker is assembled and tested at the factory prior to shipment.
This equipment was packed and shipped in factory new condition. If damage is noted, call the
carrier at once for inspection and request an inspection report. File a formal claim with the carri-
er, supported with paid freight bill, inspection report and invoice. The local ABB Sales Office must
be notified. This must be done within 10 days of receipt or receiver assumes all responsibility for
damage.
3.1 Receiving Inspection
Upon receipt, it is important to inspect promptly to be certain that the correct material has been
received. In case of shortage, immediately notify the local ABB Sales Office.
Check all parts against the shipping list as they are unpacked. Instructions and literature packed
with the breaker should be kept with the unit. The cabinet provides a convenient place to keep
this instruction book, a copy of the schematic diagram and the card with the service record of the
unit. Additional copies may be obtained upon request from the local ABB Sales Office.
If the breaker is not to be placed in service immediately, it is essential that proper care be exer-
cised in the handling and storage to ensure good operating conditions in the future. (See 3.3
Storage)
3.2 Handling
The R-MAG solid dielectric breaker comes with two brackets that attach to the sides of the cabi-
net and provide provisions for lifting the breaker. A two-point lift is recommended using the loops
in these brackets. (See Figure 2 Lifting Detail)
