Motor Control Center
The series of motor control centers integrate power cabinet and control, and have the advantages of drawer-type switch cabinets, which have been generally recognized and selected by the majority of users. In addition, this product adopts advanced new electrical components, such as fuses, circuit breakers and series contactors, which greatly reduces the size of the cabinet, improves the breaking capacity, and is superior to similar products in terms of safety and economy.
Battery performance and related technical data
The switchgear is an indoor protection type. The cabinet is made of medium-pressure bending of thin steel plates. After surface treatment with powder electrostatic spraying, it is assembled with fasteners. There is no relay compartment in the upper part of the cabinet, which can be used for installing protective relays. The cabinet is divided into two parts, the front and rear. The front part is divided into small chambers with partitions to isolate the circuits from each other. The partitions are equipped with guide rails for the movement of functional units. The plug-ins that control electrical appliances are installed on the base plate. Branch busbars are installed at the rear. The main busbar is installed on the top of the cabinet, and the branch busbars are laid vertically from top to bottom. The main busbar and branch busbars are supported by high-strength insulating parts and fixed on the cabinet.
The main electrical installation methods are divided into two structures: functional unit type and fixed type. In principle, contactors with rated currents up to and below and automatic switches below adopt functional unit structures. Feedback circuits with rated current exceeding structure.
The fixed structure is divided into compartments according to the height of the partition. Each compartment can be combined in the same cabinet according to the user's needs, but the total superimposed height does not exceed. There are three types of small chambers equipped with functional units: large, medium and small. Their heights are respectively. The three types of chambers can be combined arbitrarily. The total superimposed height is ℃

The altitude does not exceed meters

The daily average of relative humidity does not exceed, and the average value does not exceed

The earthquake rupture does not exceed degrees
