QC series magnetic starter is suitable for ship 50HZ or 60HZ power grid, used to locally control or remotely control the start/stop and operation mode of three-phase asynchronous motor, and implement short circuit, overload, phase failure and voltage loss protection for the motor. The starting mode is generally divided into direct starting, star-delta starting, autotransformer starting or variable frequency soft starting according to the increase of motor power. The operation mode is divided into single-phase operation, reversible operation, and two-speed operation. The installation method can be divided into wall-mounted type and floor-mounted type according to the size of the capacity, and the protection level can reach IP44 according to the different installation places.
Main UseFunction
Marine AC electromagnetic starter is suitable for starting, stopping and reversing operation of long-distance direct three-phase squirrel-cage asynchronous motors in AC380V/50Hz or AC440V/60Hz ship power lines. Protective function.
The product conforms to the technical standard of CB1004.1~ 1004.3- 82 "Marine AC Motor Electromagnetic Starter".
Structural Features Features:
The shell of the starter is made of steel box or screen structure, and the protection grade is IP23 or IP44. If IP56 is required, it should be specified separately.
Direct starting and star-delta starting can be divided into two structural forms: single type and combined type. The combined starter can be composed of multiple direct starters, generally with a screen structure; the independent starter is a box structure, and the autotransformer starter is a single screen structure.
The installation method of the driver: the independent type is generally wall-mounted; the combined type is generally floor-mounted or wall-mounted; the autotransformer starter is all floor-mounted (when the control power is ??300KW, the autotransformer is not installed in the The transformer box is separately made in the control panel and installed in the lower part of the starter box or the panel, and there are terminal blocks for user wiring. There are grounding studs near the wire inlet for users to ground.
