## Summary description

The Novatek-Electro RN-35 is a professional phase monitoring relay designed to protect three-phase electrical equipment. It detects phase sequence, phase loss, and voltage asymmetry in 230/400V networks. This device ensures reliable operation of industrial and domestic electrical systems by disconnecting the load during power supply faults, preventing potential damage to motors and sensitive electronic components.

## Long description

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.
