ZCT for busbars used with leakage current alarms. 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 power lines under 600V, 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: - Designed with dimensions categorized by the type of applicable circuit breakers, optimizing space utilization. - The structure is designed so that the plastic surface does not touch the busbar after assembly, minimizing thermal deformation during busbar overheating.

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.
