Zero-phase current transformer for electric wires (ZCT) 'KGC-□'
KGC-□
ZCT used with leakage current alarms. It is a product with good performance and price. ★★★ Instruments for distribution boards, control panels, distribution panels, and panels.
It is installed on a wire route with a voltage of less than 600V, allowing the overall circuit current to flow through the primary side of the current transformer, so that the vector sum of the currents is 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 passing wire. - The height of the penetration section is designed to be 45mm, considering the duct height of 40mm.

Company information
Our company was founded in 1979 and has grown from producing early analog (needle-type) instruments to digital instruments, as well as products that allow for the observation of electrical data via wireless and the internet. This development reflects the strong commitment of our employees to walk alongside our customers. Additionally, we are making proactive investments in technology development at our affiliated research institute and are thoroughly operating our business processes with a customer-centric approach. We are dedicated to meeting the diverse needs of our customers 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 under the name "LIGHTSTAR JAPAN." We also have Japanese staff on-site, and we look forward to serving you.
