Module Indicator Lamp FF LK-713K 3-phase 3×230V+N yellow red green

FF LK-713K is a modular indicator lamp assembly for three-phase electrical systems with 3×230V+N inputs, featuring yellow, red and green lenses. Intended for panel mounting in switchgear and control cabinets, this indicator lamp provides clear visual signalling of phase presence and fault/operational states in industrial and commercial installations. The compact module fits into standard cutouts and connects to the corresponding phase and neutral lines to display each phase condition independently.

Advantages

The modular design allows easy installation and replacement in control panels without altering adjacent components. Distinct yellow, red and green indicators offer immediate visual differentiation between normal operation, warnings and faults. Designed for three-phase 3×230V+N configurations, it supports direct connection to phase and neutral conductors, reducing the need for auxiliary relays or complex wiring for basic phase presence indication. The robust front lens and housing are suitable for industrial environments where reliable, continuous indication is required.

Suitable for

• Electrical switchgear and distribution panels in industrial facilities
• Control cabinets for motors, pumps and HVAC systems
• Phase presence monitoring and fault signalling in commercial installations
• Retrofit or new installations requiring visible phase indication

Key specifications

• Supply configuration: three-phase 3×230V with neutral
• Indicator colours: yellow, red, green
• Mounting type: panel-mount modular module
• Application: phase presence and status indication for control panels
• Environmental suitability: designed for typical industrial and commercial indoor electrical enclosures

How to use

Install the indicator module into a compatible panel cutout and secure it according to the panel manufacturer’s instructions. Connect each coloured indicator to the corresponding phase conductor (L1, L2, L3) and the neutral conductor as required by the 3×230V+N configuration. Verify wiring with power off, then apply power and check that each lamp illuminates according to phase presence and system state. Replace the module by isolating power, removing retaining clips or screws and swapping the unit with a matching modular indicator.

Usage recommendations

For safe operation, always de-energize circuits before installation or removal and follow local electrical codes. Verify compatibility of panel cutout dimensions and ensure connections are tight and corrosion-free. Use the module for visual phase monitoring; for protective functions or alarm integration, combine with appropriate relays or monitoring devices.
