RM-FVA voltage and current protector (3 Phase)

Key Features

1. Wide Voltage Supply Range

   • The protector is designed to work with a rated supply voltage of 380V AC, making it ideal for three-phase industrial systems.

   • It supports a wide operating voltage range of AC 50V to 400V, ensuring compatibility with various electrical networks and conditions.

2. Accurate Over-Voltage and Under-Voltage Protection

   • Adjustable over-voltage protection (U>) from 220V to 300V per phase (S/R/T).

   • Adjustable under-voltage protection (U<) from 120V to 210V per phase (S/R/T).

   • These adjustable settings allow engineers and operators to fine-tune the device to their specific system requirements, providing maximum flexibility and safety.

3. High Isolation Rating

   • With an isolation voltage rating of 440–400V, the RM-FVA ensures reliable separation and enhanced protection for connected equipment.

4. Stable Operation on Industrial Frequency

   • Operates on both 50Hz and 60Hz systems, making it suitable for global use.

 

Why You Need a Voltage and Current Protector

Three-phase power systems are widely used in industrial and commercial applications due to their efficiency in transmitting and distributing electricity. However, these systems are vulnerable to electrical issues such as voltage sags, surges, or unbalanced loads. Without protection, such disturbances can lead to:

• Equipment damage: Motors, pumps, compressors, and other machinery can be permanently damaged by repeated exposure to voltage fluctuations.

• Unexpected downtime: Power instability can cause unplanned stoppages in production, leading to losses in time and money.

• Safety risks: Electrical faults can increase the risk of fires, equipment malfunctions, and accidents.

The RM-FVA Voltage and Current Protector acts as a safeguard, constantly monitoring the incoming three-phase supply and disconnecting the load whenever unsafe voltage conditions are detected. Once the power stabilizes, it automatically restores the connection, ensuring smooth and reliable operation.

 

Applications

The RM-FVA is a versatile device suitable for a wide range of industries and settings, including:

• Industrial machinery – Protects motors, CNC machines, conveyor belts, and pumps from power fluctuations.
