Power indicator lamp with protection LK-BZ-701R 1/3S 230V 1xLED RED

Power supply control in a compact housing

The LK-BZ-701R power indicator light is a reliable device signaling the presence of voltage in the circuit. Designed for mounting on a 35 mm rail, it occupies only 1/3 of a module, saving space in the distribution board. Ideal for both professional installers and end users, it provides quick and clear information about the power status.

Functionality and safety

The device is equipped with a bright, red LED with dimensions of 8x4 mm, which ensures good visibility even in low light conditions. A built-in fuse (fast, 500 mA) protects the circuit against overload and short circuit – this protection is particularly important in electrical installations exposed to unforeseen situations. The use of a fuse with a breaking capacity of 100A at 250V AC guarantees effective protection of the device and installation.

The LK-BZ-701R indicator light offers a number of advantages: it signals the presence of 230V voltage using a red LED, and its compact dimensions (occupies only 1/3 of a module, i.e. 6.2 mm) make it ideal for tight distribution boards. Additionally, it has a built-in 500 mA fuse protecting against circuit overload and the ability to operate in a wide temperature range from -30°C to +50°C. Installation is easy thanks to the use of screw terminals (2.5 mm²) with a tightening torque of 0.4 Nm ensuring a stable connection. Low power consumption (0.15 W/channel) minimizes the impact on the overall energy consumption of the installation.

Technical specifications and application

The LK-BZ-701R indicator light is designed to monitor power in AC 230V+N circuits. The rated current per channel is 1 mA. Thanks to its reliability and ease of use, it finds application in many areas:

• Building electrical installations: Monitoring the power supply of individual circuits.
• Distribution boards: Quick identification of the power status of individual sections.
• Building automation: Signaling the power status of controllers and other automation devices.
• Industry: Monitoring the power supply of machines and production equipment.
• Workshops and service centers: Diagnostics of electrical installations and equipment.

The IP20 degree of protection provides protection against finger contact, but does not protect against the effects of water or dust – remember to provide appropriate working conditions for the device.
