Power indicator 230V/400V 3xLED green TN Type: LKM-01-20 EXT10000037

230V/400V 3xLED green power indicator – reliable voltage presence signaling

This power indicator, designated LKM-01-20, is a simple yet effective solution for optical voltage signaling in three-phase networks. Thanks to the use of three green LEDs, it clearly indicates the presence of voltage on each phase (L1, L2, L3). This is particularly useful during diagnostics and maintenance of electrical installations.

Functionality and application

The LKM-01-20 indicator is designed for mounting on a TH35 (DIN) rail, which facilitates its integration with existing switchboards. The signaling provided by high-emission LEDs ensures good visibility even in low-light conditions. The device is dedicated to TN networks with a neutral conductor (3P+N) and can operate at a rated voltage of 230/400V and a frequency of 50/60Hz.

• Three-phase signaling: Clear control of voltage presence on each phase.
• TH35 rail mounting: Quick and easy mounting in the switchboard.
• Wide voltage range: Suitable for operation in 230V and 400V networks.
• Durable construction: One-module housing provides strength and resistance to damage.
• Application in TN networks: Ideal for installations with a neutral conductor.

Technical parameters and compliance with standards

The LKM-01-20 indicator is characterized by low power consumption (0.64W) and a wide operating temperature range (-20°C ÷ +45°C). It meets the requirements of PN-EN 62094-1 and PN-EN 61000-4-2,3,4,5,6,11 standards, which confirms its safety and reliability. It also has CE and RoHS certificates, guaranteeing compliance with European environmental standards. The maximum cross-section of connection wires is 2.5 mm². The IP20 protection degree provides protection against finger contact. The device occupies one module 18mm on the TH35 rail.
