1. The circuit breaker adopts a new miniaturization design, adopts a fully enclosed structure, unique arc extinguishing chamber packaging technology, and has good sealing performance, which helps to improve moisture-proof and anti-condensation performance, and is suitable for use in high-temperature and humid areas.
2. The breaking performance of the circuit breaker is stable and reliable, and has the characteristics of no burning and explosion hazards, safety, maintenance-free, small size, light weight, and long service life.
3. The circuit breaker can be equipped with a two-phase CT, which outputs two-phase current for the function control to analyze the information and realize the over-current protection function.
4. The circuit breaker is equipped with a closing inrush current elimination device (composite controller), which can not only avoid the malfunction caused by the inrush current, but also prevent the possible errors caused by the tremor of the tripper due to the fact that the coil of the current release is not charged during normal operation.
