Product Introduction
The PBG9L explosion-proof power distribution equipment is manufactured with permanent magnet mechanism. This product is suitable for the applications with AC 50Hz circuit. The rated voltage can be 3.3 kV, 6kV, 10Kv with the rated current no more than 630A. To meet the different connection modes of the interconnected consoles, this product has four connection modes for your selection.
This PBG9L explosion-proof power distribution equipment is widely used for controlling and protecting the power network for the coal mine where it contains explosive and dangerous gas like methane, and coal dust. Additionally, the applications on the high-power motor for non-frequent start are also available for this machine.
