When it may not be suitable

This relay is not intended for high-power applications exceeding its 5A contact rating. It is also not suitable for monitoring three-phase systems without additional configuration or for environments where extreme moisture or corrosive gases are present without appropriate protective housing.

Key specifications

• Configuration: 2P (Double Pole)
• Current rating: 5A
• Voltage range: 12-400V AC
• Adjustable current thresholds: 0.1A, 1A, 10A
• Compatibility: AC and DC current monitoring

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The relay is typically mounted on a standard DIN rail within a control panel. Connect the monitored circuit to the input terminals, ensuring that the current does not exceed the specified thresholds. Use the adjustment dial or switches on the front panel to set the desired current range (0.1A, 1A, or 10A) based on your application requirements. Once wired, verify the connections and power on the system to observe the relay status indicators.

What to consider before purchase

• Verify that the maximum current of your circuit does not exceed the 5A rating
• Ensure the control voltage matches your system requirements
• Check if the available current ranges (0.1A, 1A, 10A) cover your specific monitoring needs
• Confirm that the installation environment meets the device's environmental specifications

Usage recommendations: Regularly inspect the relay for signs of wear or loose connections during scheduled maintenance. Ensure that the device is kept free from dust and debris to maintain optimal thermal performance and operational accuracy.
