Power indicator lamp LK-713 K, 3xLED, green, red, yellow, 3x230V+N, 1 module LK-713K

Three-phase power monitoring – indicator lamp LK-713K

The LK-713K indicator lamp is a reliable device designed for optical signaling of voltage presence in three-phase networks. Thanks to its clear, three-color (yellow, red, green) signaling, it allows for quick identification of the status of each phase, which is crucial for safety and effective diagnostics. Mounted on a 35mm rail, it occupies only one module, making it easy to integrate with an existing distribution board. Low energy consumption and a solid construction guarantee long-lasting and trouble-free operation.

Functionality and application

This indicator lamp is an ideal solution for both professional installers and end-users. It is used to visually monitor the power supply in three-phase 3x230V+N systems. If voltage is missing in a given phase, the corresponding LED does not light up, immediately informing about a potential problem. This simple but effective tool allows for quick detection of faults and minimizing downtime. This increases the safety of using the electrical installation and reduces the risk of equipment damage.

Construction features and parameters

The LK-713K lamp has been designed with ease of installation and use in mind. Compact dimensions (1 module – 18mm wide) allow for installation even in tight distribution boxes. Screw terminals with a cross-section of 2.5 mm² provide a secure connection of wires, and a tightening torque of 0.4 Nm guarantees connection stability. The device operates in a wide temperature range (from -25°C to 50°C) and has a protection class of IP20, which provides resistance to dust. Low power consumption (1.1 W) translates to energy savings. The rated current is 1.7 mA. The lamp uses 8x4 mm LEDs for clear signaling.
