Suitable for

• Industrial automation systems
• Motor protection circuits
• Electrical distribution panels
• Monitoring 3-phase power supply stability

This relay is not suitable for single-phase electrical systems or applications requiring voltage levels outside the specified 380-480V AC range. It should not be used in environments where the ingress protection requirements exceed the IP20 or IP40 ratings provided by the device housing.

Key specifications

• Input voltage: 380-480V AC
• Frequency: 50-60 Hz
• Protection rating: IP20 (terminals), IP40 (housing)
• Weight: 90 g
• Certifications: CSA, RCM, UL, GL, CE, CCC, EAC

The device is designed for installation on standard DIN rails within electrical enclosures. Wiring should be performed by qualified personnel in accordance with the provided technical documentation, ensuring that all phase connections are secure and correctly identified. Once installed, the relay operates automatically to monitor the network status and trigger protective actions if phase anomalies are detected.

What to consider before purchase

• Verify that your network voltage falls within the 380-480V AC range
• Ensure the installation environment meets the IP20/IP40 protection requirements
• Confirm compatibility with your existing 3-phase control system

For optimal performance and safety, ensure the relay is installed in a clean, dry environment and that all terminal connections are tightened to the manufacturer's specified torque settings.
