Description:
Maximize safety and minimize downtime with the ABB SACE Emax Installation, Service, and Maintenance Instructions. This technical manual is the authoritative resource for maintaining the classic SACE Emax series of air circuit breakers, from the compact E1 to the high-power E6.
Whether you are performing annual inspections, adjusting main contact gaps, or configuring complex protection curves on the microprocessor units, this manual provides factory-standard procedures. It is essential for electrical maintenance teams needing to troubleshoot “Trip” alarms or perform retrofitting operations.
The guide goes beyond mechanical service, offering deep insights into the PR12x series of electronic releases, helping you understand trip curves, error messages, and module connectivity.
Manual Organization & Key Technical Topics:
1. Installation & Commissioning
Mechanical Setup: Installation of fixed circuit-breakers and fixed parts for withdrawable versions.
Electrical Connections: Busbar positioning, terminal shapes, and auxiliary circuit wiring.
Racking Operations: Safe procedures for racking-in/out and handling “Disconnected,” “Test Isolated,” and “Connected” positions.
2. Maintenance Program
Routine Inspections: Schedules for general inspection (1 year) and operating mechanism checks (10,000 operations).
Contact Maintenance: Procedures for checking and adjusting contact wear (Gap A adjustment).
Lubrication: Specific grease types for the drive shaft and opening/closing shafts.
Troubleshooting: Diagnostics for “Circuit-breaker does not close/open” and “Moving part does not rack in.”
3. Electronic Protection Releases (PR121/P, PR122/P, PR123/P)
Configuration: Setting DIP switches for Thresholds (I1, I2, I3) and Times (t1, t2).
Protection Functions: Detailed analysis of functions L (Overload), S (Short-circuit), I (Instantaneous), and G (Earth Fault).
Trip Curves: Visual charts for IEC 60255-3 curves (Type A, B, C).
Error Codes: Lookup tables for alarms like “L1 Sensor,” “Trip Coil disconnected,” and “Contact wear.”
4. Accessories & Modules
Electrical Accessories: Shunt opening/closing releases (YO/YC), Undervoltage releases (YU), and Geared motors (M).
Communication: Settings for PR120/D-M (Modbus), PR120/V (Measuring), and Bluetooth modules.
Mechanical Locks: Interlocks between circuit breakers and key locks.
