Mining low-voltage circuit breaker feed switch

The mining low-voltage circuit breaker feed switch is mainly used in explosive gas environments containing methane and coal dust mixtures in coal mines and other surrounding media. It uses high-performance microprocessors for protection and monitoring, and has protection functions such as overload, short circuit, leakage blocking, leakage protection, selective leakage protection, undervoltage, overvoltage, three-phase imbalance, gas and electricity blocking, and wind power blocking. This product is easy to operate, at the same time, it has high measurement accuracy and stable and reliable protection functions.
