The working principle of STMD molded case circuit breaker adopts heat release contacts. When the current exceeds the rated value, the contacts are heated, causing the spring force to decrease, ultimately causing the contacts to move away from the contacts and cut off the power supply.
The STMD series is suitable for home, commercial, and industrial electrical systems, commonly used for the protection of AC power lines and terminal equipment, such as distribution boxes, air conditioners, lighting equipment, motors, etc. In addition, molded case circuit breakers can also be used for circuit protection in high-temperature, humid, and explosive environments.
