Novatek-Electro RN-35 Phase Sequence, Loss and Asymmetry Monitor 230/400V

The Novatek-Electro RN-35 is a professional-grade phase monitoring relay engineered to provide comprehensive protection for three-phase electrical systems. Operating within 230/400V networks, this device continuously monitors the integrity of the power supply by detecting phase sequence, phase loss, and voltage asymmetry. By automatically disconnecting the load when power faults occur, it serves as a critical safeguard for industrial machinery, motors, and sensitive electronic equipment, preventing costly damage caused by unstable electrical conditions.

Advantages

This monitoring relay offers high reliability and precision in detecting electrical anomalies that could otherwise lead to equipment failure. Its compact design allows for easy integration into standard electrical panels, while the robust internal circuitry ensures consistent performance under varying load conditions. By providing real-time protection against phase-related faults, the device significantly extends the operational lifespan of connected electrical components and reduces the risk of downtime in critical systems.

Suitable for

• Industrial motor protection systems
• Three-phase HVAC and refrigeration equipment
• Commercial electrical distribution panels
• Sensitive electronic control systems requiring stable power

This device is not suitable for single-phase electrical networks or high-voltage systems exceeding the specified 230/400V range. It should not be used as a primary circuit breaker for short-circuit protection, as it is designed specifically for monitoring phase parameters rather than managing high-current fault currents.

Key specifications

• Rated voltage: 230/400V AC
• Monitored parameters: Phase sequence, phase loss, voltage asymmetry
• Mounting type: Standard DIN rail
• Application: Three-phase electrical networks

To install the RN-35, mount the device onto a standard DIN rail within your electrical enclosure. Connect the three-phase supply lines to the designated input terminals according to the wiring diagram provided with the unit. Ensure that all connections are tightened securely to prevent overheating. Once powered, the device will automatically begin monitoring the phase parameters and will engage the internal relay to allow power to the load if the supply conditions are within the specified operational limits.

What to consider before purchase

• Verify that your electrical network voltage matches the 230/400V rating
• Ensure sufficient space is available on the DIN rail within your distribution board
• Confirm that the device meets the specific protection requirements of your connected equipment

For optimal performance and safety, ensure that the device is installed by a qualified electrician in accordance with local electrical codes. Regularly inspect the terminal connections to maintain conductivity and prevent potential faults caused by loose wiring.
