## Long description

FF LK-703K slim is a DIN-rail mounted indicator power lamp designed to monitor the presence of three separate 230 V phases plus neutral (3×230V+N). The device provides clear visual indication of supply status for control panels, distribution boards and electrical enclosures. Its slim profile reduces panel space consumption while keeping status information visible at a glance, and the product is intended for quick installation on standard DIN rails in industrial, commercial and residential electrical systems.
Advantages
The slim form factor minimizes required panel width without sacrificing visibility, allowing more components to be accommodated in the same cabinet. The lamp offers distinct indication for three-phase supplies with neutral, enabling rapid identification of phase presence. DIN-rail mounting ensures secure mechanical attachment and straightforward replacement or relocation. The design is intended for reliable continuous operation in typical low-voltage distribution environments.
Suitable for
 Monitoring three-phase 230 V supplies with neutral in distribution boards
 Control panels and switchgear status indication
 Industrial machine control cabinets and automation panels
 Commercial electrical installations and service cupboards
 Residential main distribution boards and subpanels
Key specifications
 Supply configuration: three 230 V lines plus neutral (3×230V+N)
 Mounting type: DIN-rail (standard rail profile)
 Form factor: slim profile for space-saving installation
 Function: visual presence indication of supply phases

How to use
Install the indicator power lamp on a standard DIN rail inside the distribution board or control panel, ensuring the unit is positioned for clear visibility. Connect each of the three phase conductors and the neutral conductor to the corresponding terminals following local wiring rules and safety standards. Verify correct wiring and secure terminal connections before energizing the circuit. Once powered, the lamp provides continuous visual confirmation of phase presence; inspect connections periodically as part of routine maintenance to ensure continued reliable operation.
Usage recommendations
Use the lamp in dry, indoor environments and install it in accordance with applicable electrical codes. Ensure proper overcurrent protection is present in the circuit and de-energize the panel before installation or servicing. Periodically check terminal tightness and visual indication to confirm correct phase supply and early detection of supply faults.
