Key Features:

• Electronic trip unit with LCD display showing real-time current, power, energy
• Zone Selective Interlocking (ZSI) capability for selective coordination
• Event logging: stores last 32 trip events with timestamp and fault current
• Communication: Modbus RTU (RS-485) for SCADA integration
• Rotary handle: ON / OFF / TRIP — red flag indicator for fault status

Applicable Industries: Main incoming breaker, feeder protection, motor control centers (MCC), generator protection, transformer secondary protection, large commercial buildings, industrial plants

Installation Requirements:

• Torque terminal screws to 12 Nm (for 95 mm² cable)
• Bus bar connection: use AEG copper bus bars rated ≥ 100 A
• Ensure minimum 200 mm cable bend radius at terminals
• For draw-out version: engage racking mechanism fully — do not rack under load

Usage Notes:

• Perform insulation resistance test (≥ 1 MΩ at 500 V DC) annually
• Calibrate trip unit settings using AEG testing set or commissioning software
• After fault trip, read event log via Modbus or front-panel buttons before resetting
• Coordinate upstream/downstream breakers using selectivity tables (I²t coordination)
• Replace breaker after Icu-level fault — internal arc chutes are single-use
