MNS low voltage switchgear

MNS type low voltage switchgear is suitable for 50-60Hz, rated working voltage of 660V and below power system, suitable for power plants, substations, petrochemical, metallurgical steel rolling and other industrial and mining enterprises and residential communities, high-rise buildings and other places, as an exchange 50 －60Hz, rated working voltage of 660V and below power system for power conversion and consumption equipment control.

The basic frame of the device is a combined assembly structure, all parts of the frame are galvanized, and are connected to each other by self-tapping locking screws or 8.8 grade hex screws to form the basic frame, and then add the corresponding door according to the changes in the plan. , Sealing plates, partitions, mounting brackets, bus bars, functional units and other components are assembled into a complete device. The size of parts and compartments in the device are modularized, and the protection circuit is installed separately and runs through the entire Arranged length of PE wire (or PEN wire) and conductive structural parts are composed of two parts. The metal structural parts in the device, except for the door and sealing plate of the watch, are all galvanized. The joints of the structural parts are carefully designed so that they can pass a certain short-circuit current.

An auxiliary circuit cable trough is installed on the top of the functional unit compartment, and the connecting line between the cabinets and the public power line can be placed in the trough.
