The escapement mechanism of MCB automatic change-over switch is changed from fork type to concave type, which can solve the problems such as the fracture of MCB lengthened handle and the asynchronous closure of MCB, restore the function of quick closing and quick breaking of MCB, and effectively improve the mechanical life of the product.Small size, simple structure, beautiful appearance, easy to operate, long service life.
Automatic switch does not switch when breaking handle, bonding contact or load failure (overload, short circuit), truly realize electromechanical interlock.Switch conversion drive adopts single motor drive, simple structure, reliable and stable conversion, no noise, small impact.
Switch with electromechanical interlock protection, to ensure that the automatic switch reliable operation, non-interference.Especially suitable for fire control, airport, TV station, hospital, shopping mall, bank, chemical industry, metallurgy, high-rise building and military facilities and other important places where power failure is not allowed, as an important electrical device to ensure continuous power supply.
Use level: AC- controller protection fuse breaking capacity of 50KA, improved distribution security.
Interlock is added between manual operation mode and automatic operation mode to ensure that manual operation cannot be performed under automatic condition.
