Aluminum alloy explosion-proof box device is a low-voltage distribution device that assembles switchgear, measuring instruments, protective appliances, and auxiliary equipment in a closed or semi closed metal cabinet or screen according to electrical wiring requirements. During normal operation, the circuit can be connected or disconnected using manual or automatic switches. When there is a malfunction or abnormal operation, use protective appliances to cut off the circuit or sound an alarm. It can allocate electrical energy reasonably and facilitate the opening and closing operation of the circuit. It has a high level of safety protection and can intuitively display the conductivity status of the circuit. Easy to manage and facilitate maintenance in case of circuit failure.
