Mining explosion-proof and intrinsically safe vacuum distribution feed switch

This product 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. The human-machine dialogue of the product is easy to operate, with high measurement accuracy and stable and reliable protection functions. The product has convenient communication networking and is an ideal replacement product for building digital mines.

Technical advantages and functional characteristics

1. Square switch, quick opening structure, compact and beautiful structure, with cable connectors for quick insertion of incoming and outgoing lines
2. Equipped with intelligent screen integration functions such as RS-485, Ethernet, Bluetooth, WiFi, handheld terminal APP one touch connection, and LINUX operating system.
