VL-ACB-01 — Intelligent Air Circuit Breaker, up to 690V / 6300A
The VL-ACB-01 series air circuit breakers are suitable for distribution networks with AC 50Hz or 60Hz, rated voltages of 400V or 690V, and rated currents up to 6300A. They are used to distribute electrical energy and protect lines and power equipment from overloads, undervoltage, short circuits, single-phase grounding, and other faults.
The breakers feature intelligent protection, selective protection, and accurate selective tripping to improve power supply reliability and prevent unnecessary outages. They are widely applied in power stations, factories, mining operations (especially at 690V), modern high-rise buildings, and intelligent building power distribution systems.
Standards: IEC 60947-2; GB/T 14048.2-2008.
