Electrical Safety
Permalloy Ring Core And Current Transformer For GFCI / RCD / EV charging Application When a current exceeding 30 mA passes through the human body the individual will be at serious risk of a fatal electric shock if the current is not interrupted in a timely manner. Zero phase current transformer Type A/ Type B made by Xiamen ZTC Technology Co.,Ltd is widely used in GFCI,residuel current device and other electrical safety protection device like EV Charging. These devices that shuts off an electric power circuit when it detects that current is flowing along an unintended path, such as through water or a person. It is used to reduce the risk of electric shock, which can cause the heart to stop or cause burns. They can also prevent some fires, like when a live wire touches a metal conduit.

Electric Metering
Xiamen ZTC Technology provide current transformer used for energy monitoring system. ZTC series of AC Split core current transformers with CE / ETL certificate are a simple to use, compact split-core design which is easily installed for metering applications. As energy management/monitor/audit are increasingly popular and widely applicated in home. Precision current transformer is used for some power measurement applications, the current in the device under test is higher than what can be applied directly to the power analyzer current input terminals. All of ZTC split core / precision current transformer can be tailor made to meet various projects needs. Contact us!

Celebrating 2025 Mid-Autumn Festival with Traditional Bo Bing in Xiamen
Sep 28, 2025

This Mid-Autumn Festival, our team came together to celebrate not only the season of reunion but also the local traditions that make Xiamen unique. To mark the occasion, we hosted a lively Bo Bing (Mooncake Dice Game), a cultural highlight of the festival in Fujian. The atmosphere was filled with excitement as colleagues gathered around the tables, rolling dice, sharing laughter, and competing for festive prizes. The joy and interaction created by Bo Bing reflected the spirit of teamwork, unity, and good fortune that the Mid-Autumn Festival symbolizes. More than just a game, this celebration strengthened bonds across departments, inspired morale, and reminded us of the importance of harmony and togetherness in both work and life. We look forward to carrying this energy into the months ahead, building on the same spirit of cooperation and shared success that our Mid-Autumn Festival celebration so vividly embodied. Happy Mid-Autumn Festival from all of us at ZTC!
