Zero-phase current transformer (ZCT) for electric wires 'KGC-□'
KGC-□
ZCT used with leakage current alarms. It is a product with good performance and price. ★★★ Instruments for distribution boards, control panels, sub-distribution boards, and panels.
It is designed to be installed on a wire route under 600V AC, allowing the primary side of the current transformer to carry the total circuit current, with the vector sum of the currents output on the secondary side. The output current value is measured at the input of the leakage alarm receiver. Features: - The shape of the lower section of the penetration is designed to be flat to minimize the curvature of the penetrating wire. - The height of the penetration section is designed to be 45mm, taking into account the duct height of 40mm.

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.
