## Long description

FF LK-BZ-3 K is a compact 3-pole indicator lamp combined with a fuse module designed to provide simultaneous visual status indication and overcurrent protection for three separate circuits. The unit integrates three indicator lamps and three replaceable cartridge fuse holders in a single housing, making it suitable for mounting in control panels and distribution boards where space-saving combined signaling and protection are required.
Advantages
The combined design reduces panel space by integrating indicator lamps and fuse holders into one module, simplifying wiring and installation. Replaceable cartridge fuse holders allow quick maintenance and safe replacement of fuses without removing the entire module. Clear visual indication of each circuit’s status supports rapid diagnostics and reduces downtime in industrial and commercial electrical installations.
Suitable for
 Control panels and operator consoles
 Distribution boards in industrial facilities
 Machinery and equipment requiring per-phase indication and protection
 Service cabinets and maintenance panels where compact signaling is needed
Key specifications
 Configuration: 3-pole indicator lamp with three separate fuse holders
 Fuse type: replaceable cartridge (topikowe) fuses compatible with the module
 Indication: individual visual status lamps for each circuit
 Mounting: panel-mount design for integration into control and distribution panels
 Maintenance: tool-assisted or tool-free fuse replacement depending on holder design
How to use
Install the module into a prepared cut-out in the control panel or distribution board and secure it according to panel-mount instructions. Wire each circuit to the corresponding input and output terminals, observing correct polarity and recommended wiring practices. Fit appropriate cartridge fuses into the three fuse holders before energizing the system. Monitor the indicator lamps during operation to verify circuit health; a lamp extinguished or changed in appearance indicates a blown fuse or circuit fault and requires inspection and replacement of the affected fuse.
Usage recommendations
Select cartridge fuses with correct current rating and characteristic for the protected circuit and environment. De-energize the panel before replacing fuses and follow local electrical safety procedures. Periodically inspect contacts and lamp visibility to ensure reliable indication and replace any worn or damaged components promptly.
