ABB SUE3000 1VCF750090R0804 Factory Power Supply High-Speed Circuit Breaker for Rapid Switching
I. Basic Information
Product Series: SUE3000 (ProtectIT HSTS High-Speed Power Switching System)
Order Material Number: 1VCF750090R0804
Equipment Type: Medium Voltage Plant Power Fast Switching Protection Control Device, used for millisecond-level power backup switching between two synchronous busbars to avoid power outage and shutdown of critical loads. ABB Group
Origin: Finland ABB
Core Function Parameters
Switching Speed: The fastest 1.5 power frequency cycles (approximately 30ms) complete the dual power switching, capable of implementing power-off switching of motor-type inductive loads. ABB Group
Four Switching Modes
Fast Switching (Priority Execution when Phase Conditions Are Met)
First Same-phase Switching
Residual Voltage Switching
Delayed Slow Switching
Sampling Input: Multi-channel three-phase voltage, three-phase current collection, real-time tracking of two incoming line voltage phase, frequency, and amplitude
Protection Lockout Logic: Loss of voltage on the incoming line, overcurrent, fault trip, PT disconnection, abnormal position of circuit breaker, lockout of fast switching
Fault Recording: Built-in fault recording function, can record the entire switching process of voltage and current waveforms, used for post-fault analysis
Operation Power Supply: AC/DC 48～110V universal operation power supply, supports dual power supply redundancy of AC/DC
Communication Interface: Ethernet, RS485, supports IEC 60870-5-104, Modbus, etc. protocols to connect to the background monitoring system
Human-Machine Interface: Built-in LCD liquid crystal panel + status LED indicator lights, local viewing of operating parameters, event alarms, fault records
Electrical and Environmental Specifications
Rated Frequency: 50Hz/60Hz adaptive
Analog Input: Voltage 100V (PT secondary side), current 5A (CT secondary side)
Switching Quantity: Multiple DI passive input, multiple DO relay trip/merge output
Insulation Voltage Resistance: 2kV AC power frequency voltage resistance, strong electromagnetic isolation
Operating Temperature: -25℃ ～ +55℃
Protection Grade: IP20 (embedded installation in switch cabinet)
Installation Method: Standard 19-inch cabinet plug-in installation
Net Weight: Approximately 0.75kg
Typical Application Scenarios
Power plant auxiliary power system for thermal / gas / nuclear power plants, rapid switching of working power to backup power in case of failure
Self-contained substation for continuous process high-energy-consuming enterprises such as metallurgy, petrochemical, chemical, and paper industries
Primary load critical power distribution systems for data centers, hospitals, rail transit, etc.
Medium Voltage 6kV/10kV dual incoming line single busbar distribution system, used in conjunction with REF542plus feeder protection device as a complete set of equipment. ABB Group
System Configuration for Accessories
Two common primary connection line adaptations:
Dual incoming lines + single busbar (2 circuit breaker scheme)
Dual incoming lines + two busbars + bus tie circuit breaker (3 circuit breaker scheme)
Supplementary Equipment: ABB REF542plus comprehensive protection device, VM1-T series medium voltage rapid vacuum circuit breaker, voltage/current transformers ABB Group
Supplementary Information on Model
1VCF750090R0804 is the standard IEC version order number for this device. Derivative numbers of the same series distinguish operating voltage, panel language, and communication protocol configuration; the device supports on-site parameter setting and remote debugging for downloading, enabling bidirectional incoming line mutual backup switching logic.
