Relpol RLK-3K 3-Phase Modular LED Indicator Light 400V AC Red Yellow Green

The Relpol RLK-3K is a professional 3-phase modular LED indicator designed for reliable monitoring of 400V AC electrical systems. This device provides immediate visual feedback on the status of each phase through three distinct LED lights in red, yellow, and green. Engineered for seamless integration into standard electrical infrastructure, it is housed in a compact modular casing suitable for DIN rail mounting, making it an essential component for modern distribution boards and industrial control panels.

Advantages

The primary benefit of the Relpol RLK-3K is its ability to provide real-time phase monitoring, which is critical for maintaining the safety and efficiency of electrical installations. By utilizing energy-efficient LED technology, the indicator ensures long-lasting performance with minimal power consumption and low heat emission. Its modular design allows for quick and easy installation on standard DIN rails, saving valuable space in electrical cabinets while providing a clear, high-visibility status display that can be easily read even in low-light environments.

Suitable for

• Monitoring phase presence in 400V AC industrial distribution boards
• Visual status indication in residential electrical control panels
• Electrical maintenance and diagnostic systems
• Automation and control cabinets requiring phase monitoring

When it may not be suitable

This device is specifically designed for 400V AC systems and should not be used in DC circuits or systems with voltage levels outside the specified range. It is not intended for outdoor use unless installed within a suitable IP-rated protective enclosure.

Key specifications

• Voltage rating: 400V AC
• Indicator type: LED
• Colors: Red, Yellow, Green
• Mounting type: DIN rail
• Phase configuration: 3-phase

How to use

The Relpol RLK-3K should be installed by a qualified professional in accordance with local electrical regulations. Mount the device onto a standard 35mm DIN rail within the distribution board. Connect the three phases of the 400V AC supply to the corresponding input terminals on the device. Once powered, the LEDs will illuminate to indicate the presence of voltage on each respective phase. Ensure all connections are tightened securely to prevent loose contacts.

What to consider before purchase

• Verify that your electrical system operates at 400V AC
• Ensure there is sufficient space on the DIN rail within your enclosure
• Confirm that the installation environment meets the required safety standards

Usage recommendations

For optimal longevity and safety, ensure the device is protected from excessive moisture, dust, and extreme temperatures. Regularly inspect the indicator lights during routine maintenance to confirm all phases are functioning correctly.
