Relpol RLK-3R 3-Phase LED Modular Indicator Light 400V AC Red

The Relpol RLK-3R is a high-quality 3-phase modular LED indicator light engineered for reliable status monitoring in 400V AC electrical systems. Designed for seamless integration into industrial and residential distribution boards, this compact device provides immediate visual confirmation of voltage presence across all three phases. Its robust construction and efficient LED technology ensure consistent performance and a long operational lifespan, making it an essential component for electrical safety and system diagnostics.

Advantages

The primary benefit of the Relpol RLK-3R is its ability to provide clear, real-time visual feedback on the status of three-phase power supplies. By utilizing advanced LED technology, the indicator offers high brightness and low power consumption, which significantly reduces heat generation within the electrical panel. The modular design allows for quick and effortless mounting on standard DIN rails, saving valuable time during installation and maintenance. Furthermore, the durable housing protects the internal components from environmental factors, ensuring reliable operation in demanding electrical environments.

Suitable for

• Monitoring voltage presence in three-phase industrial electrical panels
• Visual status indication in residential distribution boards
• Electrical control cabinets requiring compact signaling solutions
• Systems where rapid identification of phase failure is necessary

When it may not be suitable

This indicator light is specifically designed for 400V AC systems and should not be used in DC circuits or systems with voltage levels exceeding its rated capacity. It is not intended for outdoor use unless housed in an appropriately rated, weather-protected enclosure.

Key specifications

• Rated voltage: 400V AC
• Light source: LED
• Color: Red
• Mounting type: DIN rail
• Phase configuration: 3-phase

How to use

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is designed to be snapped onto a standard 35mm DIN rail within a distribution board. Connect the three phases to the designated terminals on the device, ensuring that the wiring is secure and follows the circuit diagram provided with the panel. Once installed, the LED will illuminate when voltage is present on the respective phases, providing an immediate visual status update.

What to consider before purchase

• Ensure the system voltage matches the 400V AC rating
• Verify available space on the DIN rail within the distribution board
• Confirm that the red light color meets your specific signaling requirements

Usage recommendations

Regularly inspect the indicator light during routine maintenance of the electrical panel to ensure all LEDs are functioning correctly and that terminal connections remain tight.
