## Long description

The Pollin WN-33P is a professional three-phase LED voltage indicator engineered for precise monitoring of 3 x 400V power supply systems. This compact device provides real-time visual feedback on the presence of voltage across all three phases, making it an essential component for modern electrical distribution boards and industrial control panels. Equipped with a built-in 1Z contact rated at 6A 250V AC, the unit also enables external signaling or automation integration, ensuring that operators are immediately alerted to phase status changes.
Advantages
The primary benefit of the Pollin WN-33P lies in its high-visibility LED indicators, which allow for instant status verification even in low-light environments. Its robust design ensures long-term reliability in demanding industrial settings, while the integrated 1Z contact adds a layer of functionality by allowing the device to trigger secondary alarms or control circuits. The compact form factor facilitates easy installation in standard electrical enclosures, saving valuable space without compromising on performance or safety monitoring capabilities.
Suitable for
Monitoring three-phase power supply systems in industrial automation
Electrical distribution boards and switchgear panels
Status signaling for machinery and production lines
Building management systems requiring phase presence detection
This device may not be suitable for applications requiring high-precision voltage measurement or digital display of exact voltage values, as it is designed primarily for status indication rather than metering. It is also not intended for use in high-voltage transmission networks or environments where the ambient temperature or humidity exceeds the specified operational limits for standard electrical components.
Key specifications
Voltage rating: 3 x 400V AC
Contact configuration: 1Z (Normally Open)
Contact rating: 6A 250V AC
Display type: LED indicators for each phase
Mounting type: Standard electrical panel installation
Installation should be performed by a qualified electrician in accordance with local safety regulations. The device is mounted directly into the electrical panel, with phase connections wired to the corresponding terminals. Ensure that the power supply is disconnected before beginning the installation process. Once installed, the LED indicators will illuminate automatically when voltage is present on the respective phases, and the 1Z contact will activate according to the internal logic of the device.
What to consider before purchase
Verify that your system voltage matches the 3 x 400V specification
Ensure there is sufficient space in your electrical enclosure for installation
Confirm that the 6A 250V AC contact rating is compatible with your signaling or control circuit requirements
For optimal performance and safety, regularly inspect the LED indicators for brightness and ensure all terminal connections remain tight and free from oxidation. Avoid exposing the device to excessive moisture or dust to maintain its operational lifespan.
