2.0 INTRODUCTION
These instructions do not attempt to provide the user of this equipment with every possible
difficulty which 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
depicted in the illustrations; however, functionality will be equivalent.
The Type R-MAG Vacuum breaker is a high-voltage, three-phase device incorporating three
vacuum 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, 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 being prepared for 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
carrier, supported with paid freight bill, inspection report, and invoice. The local ABB Sales
Office must be notified. Normally 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 carrying 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
exercised 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
cabinet and provide provisions for lifting the breaker. A two-point lift is recommended using
the loops in these brackets. (See Figure 2)
