FF LK-703G 3-Phase Modular LED Indicator Light, Green, 230V, 0.5 Module

The FF LK-703G is a professional 3-phase modular LED indicator light designed to provide reliable visual status monitoring for electrical systems. Engineered for installation on standard DIN rails, this device features a highly compact 0.5-module width, making it an excellent choice for space-constrained electrical distribution boards. Operating at 230V AC, it delivers clear green light signals to indicate the presence of voltage across three phases.

Advantages

The primary benefit of this modular indicator is its space-saving design, which occupies only half the width of a standard module, allowing for more efficient use of space in crowded distribution panels. The use of high-quality LED technology ensures long-lasting performance, low power consumption, and high visibility under various lighting conditions. Its robust construction is specifically tailored for both industrial and residential electrical environments, ensuring consistent operation and easy integration into existing setups.

Suitable for

• Monitoring 3-phase power supply status in distribution boards
• Visual indication of voltage presence in industrial control panels
• Residential electrical installations requiring compact monitoring solutions
• Status signaling in modular automation systems

When it may not be suitable

This indicator is designed exclusively for 230V AC systems and should not be used in DC circuits or high-voltage applications exceeding its rated specifications. It is not intended for outdoor use unless housed in a suitable weather-resistant enclosure.

Key specifications

• Operating voltage: 230V AC
• Number of phases: 3-phase
• Mounting type: DIN rail (TH35)
• Width: 0.5 module
• Light color: Green
• Technology: LED

How to use

The device is designed for simple snap-on mounting onto a standard 35mm DIN rail. Electrical connections should be made by a qualified professional in accordance with the wiring diagram provided on the device housing. Ensure that the power supply is disconnected before installation. Once securely mounted and wired, the indicator will automatically illuminate when voltage is applied to the respective phases.

What to consider before purchase

• Verify that your distribution board has a 0.5-module space available
• Ensure the system voltage matches the 230V AC rating
• Confirm that the green light color meets your specific signaling requirements

Usage recommendations

For optimal longevity and safety, ensure that the indicator is installed in a clean, dry environment and that all terminal connections are tightened to the manufacturer's specified torque settings.
