## Long description

The Finder 70.41.8.400.2030 is a professional 3-phase voltage monitoring relay engineered for industrial and electrical infrastructure. This device provides comprehensive protection by continuously monitoring power quality within 380-415V AC systems. It is designed to detect critical electrical faults, including phase loss, incorrect phase sequence, asymmetry, and neutral conductor issues, ensuring that connected equipment remains protected from unstable power conditions.
Advantages
This monitoring relay offers high operational reliability through its integrated safety logic, which opens the contact immediately upon detecting a fault. The device features front-accessible controls for easy adjustment and clear LED status indicators for quick diagnostics. Its robust design is suitable for standard DIN rail mounting, making it a versatile choice for modern control panels and automation systems. The inclusion of selectable neutral monitoring adds an extra layer of safety for complex electrical installations.
Suitable for
Industrial control panels
Automation and motor control systems
Power distribution monitoring
Protection of sensitive electrical equipment
Three-phase electrical networks requiring neutral monitoring
This relay may not be suitable for applications requiring voltages outside the specified 380-415V AC range or for environments with extreme environmental conditions that exceed the IP20 protection rating. It is not intended for use in high-current power circuits that exceed the 6A switching capacity without the use of additional contactors or relays.
Key specifications
Operating voltage: 380-415V AC (50-60 Hz)
Monitoring range: 300-480V
Contact configuration: 1 changeover contact (SPDT)
Switching current: 6A
Switching voltage: 250V AC (max 400V AC)
Switching delay: 0.5 to 60 seconds
Mounting: DIN rail EN 60715 TH35
Operating temperature: -20 to +60 °C
Protection rating: IP20
Installation should be performed by qualified personnel in accordance with local electrical regulations. The device is designed for mounting on a standard 35mm DIN rail. Once mounted, the front-facing controls allow for the configuration of monitoring parameters. Ensure that the wiring is securely connected to the terminals and that the neutral conductor is correctly identified if neutral monitoring is required. The LED indicators will provide visual feedback on the operational status of the relay.
What to consider before purchase
Verify that your system voltage matches the 380-415V AC requirement.
Ensure the 6A switching capacity is sufficient for your load or plan for an external contactor.
Confirm that the DIN rail space is available in your control panel.
Check if your specific application requires neutral conductor monitoring.
For optimal performance and safety, regularly inspect the relay for signs of wear and ensure that all terminal connections remain tight. Test the monitoring functions periodically to confirm that the relay triggers correctly during simulated fault conditions.
