RVSF0-040 is a three-phase voltage monitoring and protection device designed for electrical control systems. With 3×400VAC voltage display, phase protection and over/under voltage protection functions, it helps monitor power supply conditions and improve the safety of industrial electrical equipment.
Based on ATST Electric’s core concept of “Precise Control, Safe and Reliable”, RVSF0-040 Other Series provides a practical solution for three-phase voltage monitoring and electrical protection applications. In industrial electrical systems, unstable voltage, phase problems and abnormal power supply conditions may affect motors, pumps, compressors, HVAC equipment and control panels. RVSF0-040 helps monitor the three-phase voltage status and provides protection support when abnormal power conditions occur. The product catalog shows that RVSF0-040 supports 3×400VAC voltage display, 5A load current, phase protection and over/under voltage protection. This makes it suitable for applications where engineers need both voltage indication and electrical protection in control cabinets or distribution systems. With compact structure, low-power contact load and easy panel integration, RVSF0-040 helps improve system visibility, reduce electrical fault risks and support stable equipment operation.
