Leakage current fire alarm receiver (controller) 'KGD'
KGD-□□□
Leakage current fire alarm installed for the purpose of preventing leakage accidents ★★★ Instruments for distribution boards, control panels, distribution panels, and panels.
As a device installed to prevent leakage accidents on wiring routes below 600V AC, it inputs the current measured by a zero-sequence current transformer (ZCT) and outputs alarm signals and alarm sounds when the measured value exceeds the preset value for each circuit, enabling remote monitoring through communication and control signals.

Company information
Our company was founded in 1979 and has grown into a manufacturer of products that can observe electrical data through early analog instruments, digital meters, wireless, and the internet. This development is driven by the strong will of our employees to walk alongside our customers. Additionally, we are committed to thorough customer-centric operations while actively investing in technological development at our affiliated research institute. We strive to meet our customers' diverse needs through more differentiated services. In our case, we have become well-known in South Korea for our measuring instruments (analog, digital meters, and CT, VT). We have been exporting to Japanese companies for over a decade, and we have registered with Ipros to introduce our products to more Japanese customers. In 2022, we registered as a corporation in Tokyo and have since relocated our corporate office to Osaka as "LIGHTSTAR JAPAN." We also have Japanese staff on-site, and we look forward to your support.
