## Long description

The Pollin WN-3F is a professional 3-phase LED voltage indicator engineered for the continuous monitoring of electrical systems operating at 3 x 400V AC. This compact device is designed for seamless integration into electrical distribution boards, providing an immediate visual confirmation of voltage presence across all three phases. By utilizing high-visibility LED technology, it ensures that maintenance personnel and users can quickly verify the status of the power supply, contributing to enhanced safety and operational efficiency in both industrial and residential environments.
Advantages
The primary benefit of the Pollin WN-3F is its ability to provide real-time status updates for complex 3-phase electrical systems. Its compact design allows for easy installation on standard TH35 DIN rails, which are common in modern electrical enclosures. The use of energy-efficient LED indicators ensures long-term reliability and low power consumption, while the clear layout allows for rapid diagnostic checks without the need for additional measuring instruments. This device simplifies the monitoring process, helping to prevent downtime by identifying phase failures or power interruptions instantly.
Suitable for
Monitoring 3-phase power supply in residential distribution boards
Industrial electrical control panels and automation systems
Commercial building power distribution monitoring
Verification of phase presence in electrical installations
When it may not be suitable
This device is not intended for precise voltage measurement or displaying numerical voltage values, as it only provides a visual indication of phase presence. It is strictly designed for 400V AC systems and should not be used in DC circuits or systems with voltage levels outside of its specified operating range.
Key specifications
Operating voltage: 3 x 400V AC
Mounting type: TH35 DIN rail
Display type: LED indicators
Phase count: 3-phase
How to use
The Pollin WN-3F should be installed by a qualified electrician in accordance with local electrical safety regulations. The device is designed to be snapped onto a standard TH35 DIN rail within a distribution board. Once mounted, the input terminals must be connected to the corresponding phases of the 3-phase power supply. After the power is restored, the integrated LEDs will illuminate to indicate that voltage is present on each respective phase. No further configuration or calibration is required for operation.
What to consider before purchase
Ensure your electrical system operates at the specified 3 x 400V AC voltage
Verify that there is sufficient space on your TH35 DIN rail for installation
Confirm that the installation environment is free from excessive moisture or extreme temperatures
Usage recommendations
Regularly inspect the LED indicators to ensure all phases are active. If one or more LEDs fail to light up while the system is powered, perform a diagnostic check on the corresponding phase to identify potential power supply issues.
