Indicator light RLK-3K 863028

Phase sequence indicator RLK-3K is a reliable signaling device designed for visual monitoring of the status of three-phase circuits. Equipped with three LEDs – red, yellow, and green – it provides clear and readable information about the correct operation of the installation or the occurrence of irregularities. It is a key tool for both installers during commissioning and testing of systems, and for end-users who want to have ongoing control over the power supply status.

Characteristics and application

The RLK-3K control lamp is designed for mounting on a 35 mm rail, which facilitates its integration with existing electrical distribution boards. Its compact dimensions (width 17.5 mm, height 64.5 mm, depth 90 mm) allow for installation even in limited spaces. AC 230/400V (50/60 Hz) power supply guarantees compatibility with most standard electrical installations. Low power consumption (≤ 1.1 W) minimizes the impact on energy consumption.

The device finds application in:

• Industrial electrical distribution boards: signaling the phase status in motors, transformers and other devices.
• Distribution boards: control of the power supply to individual circuits.
• Automation systems: visual information about the operating status of control devices.
• Workshops and service centers: assistance in diagnosing and repairing electrical equipment.

Construction and product features

RLK-3K is characterized by a solid construction and high quality workmanship. The housing with IP20 protection degree provides basic protection against touch and dust. Three-color LEDs provide clear signaling:

• Green: indicates correct circuit operation.
• Yellow: signals a warning status or irregularity requiring attention.
• Red: informs about a serious problem or failure requiring intervention.

Mounting on a TH-35 rail facilitates quick and safe installation without the need for additional tools or fixing elements. Low energy consumption means that the indicator can operate continuously without generating significant operating costs. Additionally, the compact size allows it to be placed in places with limited space without losing functionality.
