KJG-6(10) Y
6kV/10kV Mining Flameproof and intrinsic safety Electromagnetic Switch for Mobile Substation
Functions:
This product is mainly used in underground coal mines, where there are mixed explosive gases, such as methane. It is used to control the power distribution system for the mobile substation, with rated voltage 10kV, rated frequency, and rated current up to 400A. It works with BXB1 series Lower Voltage Protection Cabinet to form an idealized mobile substation system.
Features:
Advanced CPU technology is adopted to protect the power system from damage of overload, electric leakage, short-circuit, wind power gas, and over or under voltage. It has long-term memory to the reason of overload tripping.
It is small in size and the circuit breaker can be switched on or off manually or automatically.
It is compatible with all large capacity mobile substations( under 2500KVA)
The circuit-opening device is the manually operated knife switch.
