## Summary description

The Pollin WN-3BK is a 3-phase modular indicator light featuring yellow, red, and green signals for clear status monitoring in electrical panels. It is designed for 10-250V AC operation and includes an integrated 5x20mm fuse holder with a 100mA fuse for circuit protection. This compact modular device is ideal for industrial and commercial control systems requiring reliable visual phase indication.

## Long description

The Pollin WN-3BK is a professional 3-phase modular indicator light designed for clear and reliable status monitoring in electrical distribution boards and control panels. This compact device features three distinct LED indicators in yellow, red, and green, allowing for immediate visual verification of phase presence. It is engineered to operate within a voltage range of 10-250V AC and includes an integrated fuse holder compatible with standard 5x20mm fuses, ensuring an additional layer of circuit protection for the indicator unit.
Advantages
The primary advantage of this modular indicator is its space-saving design, which fits standard DIN-rail configurations commonly found in industrial and commercial electrical enclosures. By providing three color-coded signals in a single housing, it simplifies panel layout and reduces the number of individual components required for phase monitoring. The inclusion of a dedicated fuse holder directly on the device enhances safety by protecting the internal circuitry against overcurrent, while the wide operating voltage range ensures compatibility with various electrical systems.
Suitable for
Industrial control panels and automation systems
Commercial electrical distribution boards
Three-phase power supply monitoring
Electrical maintenance and diagnostic equipment
When it may not be suitable
This device is not intended for use in high-voltage DC applications or environments exceeding the specified 250V AC limit. It is also not suitable for outdoor installations without an appropriate weather-resistant enclosure, as the unit is designed for indoor panel mounting.
Key specifications
Operating voltage: 10-250V AC
Indicator colors: Yellow, Red, Green
Fuse type: 5x20mm
Fuse rating: 100mA
Mounting type: Modular DIN-rail
How to use
The indicator should be installed by a qualified professional in accordance with local electrical regulations. Mount the unit onto a standard DIN rail within the electrical panel. Connect the phase lines to the corresponding input terminals of the device. Ensure that the 100mA fuse is properly seated in the integrated holder before energizing the circuit. Once installed, the lights will illuminate automatically when power is present on the respective phases.
What to consider before purchase
Verify that your control panel has sufficient space on the DIN rail
Ensure the operating voltage of your system falls within the 10-250V AC range
Confirm that a 100mA fuse is appropriate for your specific monitoring circuit requirements
Usage recommendations
Regularly inspect the indicator lights and the fuse status during routine maintenance to ensure continuous monitoring capability. If a light fails to illuminate while the phase is active, check the integrated fuse for continuity and replace it if necessary using a 5x20mm 100mA fuse.
