Features 1、Small size, simple structure, beautiful appearance, easy to operate, long service life. 2、Switch conversion drive adopts single motor drive, simple structure, reliable and stable conversion, no noise, small impact. 3、Switch with electromechanical interlock protection, to ensure that the automatic switch reliable operation, non-interference. 4、Use level: AC- controller protection fuse breaking capacity of 50KA, improved distribution security. 5、Interlock is added between manual operation mode and automatic operation mode to ensure that manual operation cannot be performed under automatic condition. Specification Overview: Features: Small size, simple structure, beautiful appearance, easy to operate, long service life. 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. The switch can automatically change the load, and the handle can be used to switch manually in case of emergency. 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. Automatic switch does not switch when breaking handle, bonding contact or load failure (overload, short circuit), truly realize electromechanical interlock. 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.
