Pollin WN-3FK-P 3-Phase Modular Indicator Light, Yellow/Red/Green, 10-250V AC with TEST Button

The Pollin WN-3FK-P is a high-quality 3-phase modular indicator light designed for seamless integration into electrical distribution boards. This compact device provides clear visual status monitoring for three-phase electrical systems using distinct yellow, red, and green LED indicators. Engineered to operate within a wide voltage range of 10-250V AC, it ensures versatility across various electrical setups. The inclusion of a dedicated TEST button allows users to verify the operational status of the indicators instantly, ensuring safety and reliability in monitoring tasks.

Advantages

The primary benefit of this modular indicator light is its ability to provide real-time visual feedback on phase presence, which is critical for maintaining electrical system integrity. Its modular design allows for easy installation on standard DIN rails, saving space and time during assembly. The wide operating voltage range makes it compatible with diverse power environments, while the integrated test function simplifies maintenance by allowing quick checks without the need for external testing equipment.

Suitable for

• Monitoring phase presence in industrial electrical panels
• Residential distribution board status indication
• Electrical control cabinets requiring compact visual alerts
• Systems where rapid verification of phase status is necessary

When it may not be suitable

This device is designed specifically for AC circuits and is not suitable for DC power applications. It should not be used in environments where the voltage exceeds the specified 250V AC limit or in highly corrosive atmospheres that could damage the modular housing.

Key specifications

• Voltage range: 10-250V AC
• Phase configuration: 3-phase
• Indicator colors: Yellow, Red, Green
• Mounting type: Modular DIN rail
• Integrated features: TEST button

How to use

The indicator light is designed for mounting on a standard DIN rail within an electrical distribution board. Ensure the power is disconnected before installation. Connect the phase wires to the corresponding terminals on the device according to the wiring diagram. Once installed and powered, the LEDs will illuminate to indicate the presence of voltage on each phase. To verify the functionality of the LEDs, press the TEST button, which will simulate the signal and confirm that all indicators are operating correctly.

What to consider before purchase

• Verify that your electrical system operates within the 10-250V AC range
• Ensure there is sufficient space on your DIN rail for a modular device
• Confirm that the phase configuration matches your three-phase installation

Usage recommendations: Regularly use the TEST button during routine maintenance inspections to ensure all phase indicators remain fully functional and visible.
