The TCVA1 voltage and current protector is a new type of intelligent protector. The product adopts a modular design, and can adjust the circuit overvoltage, undervoltage, and overcurrent. The protector can quickly cut off the circuit to avoid equipment damage caused by abnormal voltage or current connected to terminal appliances. When the voltage or current returns to normal, the circuit will be automatically connected within the time delay, so as to ensure the normal operation of the terminal under unattended conditions, and the voltage and current values can be displayed at the same time.

Adhering to the principle of providing cost-effective, stable and qualified products to the market, it has now expanded to 17 countries including North America, Europe, and the Middle East. Its products have also expanded from traditional low-voltage electrical products to intelligent products.
Q: The future development direction of the company
A: The company will mainly develop breakthroughs in the following areas in the future
1. Improvement of product quality and reliability
With the continuous advancement of technology, the product quality and reliability of low-voltage electrical appliances have been significantly improved. Domestic low-voltage electrical appliances have no significant difference in basic performance compared to overseas brands, and even perform well in some aspects. For example, the domestically produced 160A molded case circuit breaker is comparable to international brands such as Schneide in terms of power supply continuity, and has a higher cost-effectiveness.
2. Digitization and intelligence
Electronics and intelligence are important directions for the development of low-voltage electrical appliances. Digitization enables low-voltage electrical appliances to better integrate advanced electronic technology, improving their control accuracy and response speed. Intelligence integrates technologies such as the Internet of Things and big data analysis to enable remote monitoring, fault warning, and automatic adjustment of low-voltage electrical appliances, thereby improving the overall efficiency and reliability of the system.
3. Product modularization and modularization
In order to meet diverse market demands, low-voltage electrical products are developing towards modularization and modularization. This trend makes products more flexible, and users can choose appropriate modules to combine according to specific needs, thereby reducing overall costs and improving the maintainability and scalability of the system.
