    ABB, might be done or of the possible hazardous consequences of each conceivable way, nor could ABB investigate all such ways. Anyone using service procedures or tools, whether or not recommended by ABB, must satisfy himself thoroughly that neither personal safety nor equipment safety will be jeopardized by the service method or tools selected.

  • Page 6: Introduction

    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.

  • Page 7: General Description

    38-929M-15A 10/15/02 1:11 PM Page 7 Caution - Exercise care during lifting to avoid damage to the bushings. Breaker has high center of gravity. Figure 2. Lifting Detail 3.3 Storage For prolonged storage, indoor storage is recommended. If stored outdoors, the cabinet heaters must be energized to maintain warranty.

  • Page 8: Standard Production Tests

    Disassembly of the magnetic actuator is not necessary nor recommended. Lubrication or maintenance is not required. Should an actuator fail to operate, contact ABB for service. The permanent magnet inside the actuator is extremely powerful with the potential to trap fingers.

  • Page 9: Operational Checks Prior To Installation

    38-929M-15A 10/15/02 1:11 PM Page 9 6.2 Opening When the bottom coil is energized, the magnetic flux generated opposes the force generated by the magnet assembly. This reduces the holding force, the armature is released and the coil attracts the armature to the bottom plate. Once there, it is held open by the magnet. 7.0 OPERATIONAL CHECK PRIOR TO INSTALLATION The breaker should be tested for mechanical and electrical operation before delivery to the installation site.

  • Page 10: Installation

    38-929M-15A 10/15/02 1:11 PM Page 10 TEST PROCEDURE RADIATION WARNING: High voltage applied across an open gap in a vacuum can produce X-radiation. No radiation is emitted when the interrupter is closed since no gap exists. Also, when the breaker is open to the specified contact spacing in service or tested within the voltages specified, X-radiation at one meter is below the level of concern.
  • Page 11 All ground wire used must be #6 AWG minimum. 8.3 Arrester Protection ABB recommends that surge arresters be properly applied in the substation. 8.4 Control Power Supply the control power as indicated on the wiring diagram. If 240 VAC is used, verify the connections for the heaters before applying power.

  • Page 12: Inspection, Maintenance And Adjustment

    38-929M-15A 10/15/02 1:11 PM Page 12 9.0 INSPECTION, MAINTENANCE AND ADJUSTMENT The R-MAG is an extremely simple device and will require minimal maintenance depending on the frequency of operation and local environmental conditions. The safety and successful functioning of any apparatus or system connected with the breaker depends to a large extent on the proper and reliable operation of the unit.
  • Page 13 38-929M-15A 10/15/02 1:11 PM Page 13 D. If internal flashover occurs, isolate the phases and test each one independently to identify the defective interrupter. Any defective pole assembly must be replaced prior to the breaker being in service. 5. Contact Resistance: Measure contact resistance with suitable equipment rated not less than 100 A.
  • Page 14 38-929M-15A 10/15/02 1:11 PM Page 14 9.2 Contact Travel and Over-Travel Adjustment (See Figure 7) With the breaker in the open position: 1. Loosen Locknut (F) on Bolt Stem (E). 2. Remove Pin (B) while applying pressure from the back of the Contact Block. Allow Contact Block to move slowly to closed position.
