ABB GRID BREAKER UNIT GBU72 3BHE055094R0002 / 3BHE031197R0001 / 3BHB030310R0001
Product Name
3BHE055094R0002 GBU72 Industrial Grid Breaker Control Module (ABB Medium-Voltage Switchgear Protection Unit)
Product Description
The 3BHE055094R0002 GBU72 is a high-performance grid breaker control module by ABB, tailored for medium-voltage (10kV-35kV) switchgear in power distribution networks. It integrates real-time monitoring, protection, and control of circuit breakers, ensuring safe and stable grid operation. Widely used in industrial plants, renewable energy substations, and urban distribution systems, it quickly responds to faults (e.g., short circuits) by triggering breaker trips within milliseconds, minimizing fault impact. In solar/wind farms, it coordinates with inverters for smooth grid connection, maintaining power quality. With a rugged design, it operates reliably in harsh environments, boasting strong anti-interference and high precision, making it vital for modern power distribution automation.
Product Parameters
- Electrical I/O: 16 DC 24V digital inputs (response <1ms), 4 4-20mA analog inputs (±0.2% FS accuracy), 8 Form-C relays (5A at 250V AC/30V DC).
- Power: Dual redundant DC 110V/220V (±15%), 80mA (no-load) to 300mA (full load).
- Communication: RS485 (Modbus RTU, 9600-115200bps), Ethernet (Modbus TCP/IP).
- Protection: Overcurrent (0.5-10x rated current, 0-10s delay), over/undervoltage (20%-120% rated voltage), breaker failure (50ms-2s timeout).
