Pollin WN-3BK 3-Phase Modular Indicator Light Yellow/Red/Green with 5x20mm Fuse 100mA 10-250V AC

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.
