Solar System Molded Case Circuit Breaker

The solar system molded case circuit breaker uses high-strength plastic or metal materials to make the shell, and contains key components such as contacts, fuses and electromagnetic releases inside. It can quickly cut off the circuit when the current exceeds the rated value, thus preventing the electrical equipment in the solar system from being damaged due to overload or short circuit.
