In today’s world, where technology is advancing at an unprecedented rate, the demand for safe and reliable electrical equipment is constantly on the rise. One such piece of equipment, the China Photoelectric Automatic Circuit Breaker (MCCB), has found its way into numerous applications across various industries.
The China Photoelectric Automatic Circuit Breaker (MCCB), also known as the Miniature Circuit Breaker, is a highly versatile automatic switching device designed to protect electrical circuits from overload and short-circuit conditions. It is manufactured using a combination of advanced photoelectric technology and automated production processes, ensuring high performance and reliability. The working principle of the MCCB is based on the photoelectric effect, which involves the conversion of light into electrical energy. In the MCCB, this effect is utilized to sense the amount of current flowing through the circuit. When the current exceeds a pre-set limit, a photoelectric sensor trips the mechanism, breaking the circuit and preventing further damage.
