Power supply status indicator light 3xLED green, slim 1/3 module LK-703G

3-phase control lamp – quick power supply status indication

This compact LK-703G control lamp from F&F is a reliable tool for visually checking the presence of voltage in 3-phase networks. Its slim design, taking up only 1/3 of a module on the rail, saves valuable space in the distribution board. Thanks to three green LEDs (one for each phase), you can quickly identify which phases are energized.

Functionality and application

The LK-703G lamp is designed for mounting on a standard 35 mm rail and connected using screw terminals (2.5 mm²). It indicates the presence of voltage in networks with a value of 24V, 110V or 230V (depending on the model – check the marking). It is ideal for use in control cabinets, electrical switchboards and anywhere where quick and clear information about the power supply status of individual phases is required.

Worth knowing: When using overcurrent fuses with a value above 25A before the lamp, it is recommended to additionally protect the lamp circuit with a fuse not greater than 6A. This will ensure its proper operation and protection against damage.

Key features and benefits

• Compact size: Occupies only 1/3 of a module (6.2 mm wide), making it easy to install even in crowded distribution boards.
• Visual indication: Three green LEDs clearly indicate the presence of voltage in each phase.
• Universal supply voltage: Available versions for voltages of 24V, 110V and 230V – choose the appropriate one for your installation.
• Easy installation: Quick mounting on a standard 35 mm rail and simple connection of wires using screw terminals.
• Wide operating temperature range: Trouble-free operation at temperatures from -30°C to +50°C.
• Low power consumption: Energy consumption at only 0.15 W per channel minimizes energy losses.
• Durable construction: Ensures long-lasting and reliable operation in harsh industrial conditions (IP20 protection).

Thanks to these features, the LK-703G lamp is a practical solution for both professional installers and end users looking for a reliable way to monitor the power supply status in their electrical installations.
