Figure 1. Hazardous Voltage Nameplate 1.0 SAFETY NOTICES Install the R-MAG circuit breaker within the design limitations as described on its nameplate and in these instructions. Follow your company’s safety procedures. This breaker should not be used by itself as the sole means of isolating a high voltage circuit. For...
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)
4.0 GENERAL DESCRIPTION 4.1 High-Voltage Assembly The high-voltage section of the R-MAG consists of three individual phase assemblies mounted on insulating standoffs. Each phase of the R-MAG consists of a single vacuum interrupter, flexi- ble shunt and operating rod. 4.2 Housing The doors of the breaker housing are removable and retained by hinge pins.
4.5 Standard Control (ED2.0) The standard control package of the R-MAG is the ED2.0. The ED2.0 consists of a power supply, position indication and capacitor charging/discharging system. Refer to Appendix A for an overview of the ED2.0.
6.2 Opening When the bottom coil is energized, the magnetic flux opposes the force generated by the magnet assembly. This reduces the holding force, the armature is released and the coil attracts the arma- ture 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 installa- tion site.
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 con- nections for the heaters before applying power.
9.0 INSPECTION, MAINTENANCE AND ADJUSTMENT The R-MAG circuit breaker is an extremely simple device and requires 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 largely depends on the proper and reliable operation of the unit.
Any defective pole assembly must be replaced prior to the breaker being in service. 9.2 Replacement of Vacuum Interrupter Assemblies (See Figures 3-8) The following procedure is made with the R-MAG breaker in the open position, control power off and locked out, and stored energy capacitors discharged. CAUTION If power is removed from unit, and the Dip Switch I1004-1 is placed in the “on”...
7. Support the moving contact of the vacuum interrupter at the contact block (C) and loosen the nut (F) taking care not to apply any torque to the end of the vacuum interrupter as damage may result. (Figures 8). 8. With the stem nut loose (F), install the shoulder pin and washers through the triangular bell- cranks) to the bolt stem (B) (E) and fasten with the new locknut provided.

APPENDIX A INSTALLATION / MAINTENANCE INSTRUCTIONS R-MAG Medium Voltage Vacuum Power Circuit Breaker ED2.0 MAGNETIC ACTUATOR CONTROL BOARD...
1.0 OVERVIEW The ED2.0 electronic control board is comprised of a Power Supply Recharge Unit, Control Unit, and FET Switching circuit which connects the Storage Unit Capacitors to the Magnetic Actuator coils. The power supply recharge circuitry adapts whatever input voltage, within the specified range (Section 2.0), is supplied to maintain an 80 V charge voltage across the capacitors.
20 milliamperes. The input impedance (Z) is 300 kOhms except for binary inputs 1 and 2 (Remote open and close) which are around 14 kOhms input Z. There are seven different input channels. Only six of them are used for the R-MAG breaker (channel 5 is not used).
3.4 Protection Trip / Second Trip (KM1005, CH 4, Pins 7 and 8) This input can be configured as either a Protection Trip or Second Trip function. It is programmed via Jumper JP1001 Pins 1 and 2 or as a normal input by jumpering JP1001 pins 2 and 3. The Protection Trip input is designed to work at a lower threshold of 7 VDC.
4.0 BINARY OUTPUTS Binary outputs are simply pairs of mechanical wipe relay contacts. They can be employed to switch in other circuitry or to an alarm indicator. See Illustration 3 and 4 for the power limitations of the contacts. Notice the flat curve for AC voltage in Illustration 4. On the inside of the low volt- age cabinet there is a membrane style button plate that contains a “Ready”...

Recharge Unit is 80% efficient. This means that the Auxiliary Power supply input must be at least 93.75 W for the 75 W setting or 41.3 W for the 33 W setting. The 33 W option is hardware selec- table with Jumper JP1019. 5.6 RS-232 Port / JTAG Communication Port Used by ABB factory only.
6.0 POWER CONSIDERATIONS The ED2.0 power supply recharge unit adapts any voltage within the specified range of the board to maintain 80 V across the capacitors. The following voltage thresholds must be reached to complete the specified operations: 1. The capacitor voltage threshold for an Open operation is 49 volts. 2.
The ED2.0 board provides access through KM1003 for discharging the Storage Unit capacitors. Make sure the ED2.0 Control Board Power is removed before attempting to discharge the capac- itors. PROCEDURE: A 10 kOhm capacitor discharge resistor is mounted on the circuit board. Discharging is done by jumpering KM1003 pins 4 and 5.
8.0 DEFAULT JUMPER AND DIP SWITCH SETTINGS REV 02 AND GREATER ED2.0 Unless specified by the customer, the Low Energy and Under Voltage trip functions are disabled. Input three is set for Auxiliary trip mode as opposed to the Protection Relay trip mode. The Protection Relay mode has a lower switching threshold (12 V).
10.0 INSTRUCTIONS FOR TROUBLESHOOTING AN ED2.0 CONTROL BOARD The Power Supply recharge circuitry either reduces (high voltage board) or increases (low volt- age board) input voltage within the specified range supplied to maintain an 80 V charge voltage across the capacitors. The Control Unit monitors binary inputs and outputs, hardware and software configurations, posi- tion sensors, capacitor charge, and switches the FET circuit to connect the capacitor voltage to the magnetic actuator coils following an open or close command.
