Medium voltage air-insulated switchgear for 12kV primary distribution, delivering reliable and cost-effective power switching solutions.
GCK LV withdrawable switchgear: Enables easy component access and maintenance in low - voltage systems, ensuring efficient power distribution.
MNS is modular low voltage withdrawable switchgear for three-phase AC 50Hz system, rated operational voltage up to 690V, used for industrial and commercial low voltage power distribution and motor control.
It adopts compact modular assembled cabinet structure. Each functional unit is withdrawable. The drawer unit can be isolated and replaced without cutting off the main busbar, reducing maintenance downtime.
Complete mechanical interlock mechanism prevents misoperation. The drawer can only be moved between working, test and isolated positions under switch-off status to ensure operator safety.
Different protective components can be configured to achieve overload, short-circuit and earth fault protection for feeders and motor control circuits.
Smart power meters, temperature sensors and communication modules are optional to collect voltage, current, power and cabinet temperature data for remote monitoring and SCADA connection.
