Description of kt12-25j / 1 25J / 5 cam controller:

Kt12 series AC cam controller

Purpose and model significance

Kt12 Series Cam controller includes:? In the circuit of 0Hz and voltage up to 380V, it is mainly used for direct action, speed regulation and commutation of starter.

The model and meaning of cam controller are as follows:

1. Classification, model and meaning

The controller is divided according to the type and quantity of motors controlled by pumping:

Kt12-25j / 1 cam controller is used to control a three-phase winding induction motor.

Kt12-25j / 2 cam controller is used to control two three-phase winding induction motors at the same time, with contacts of stator circuit.

Kt12-25j / 3 cam controller is used to control a three-phase squirrel cage induction motor.

Kt12-60j / 2 cam controller is used as a contact with stator circuit to control two three-phase winding induction motors at the same time.

Kt12-60j / 3 cam controller is used to control a three-phase squirrel cage induction motor controller.

2. Structure and characteristics

According to the operation mode, it is divided into handwheel type and handle type

The controller is protective and made into a protective contact system, which is composed of single element building blocks. The contact is rotary and single breakpoint. The arc extinguishing cover (made of steel plate) is directly fixed on the contact elements. The contact elements are arranged in double rows, and the upper and lower panels, bases and hand wheels are made of thermoplastic materials.

Structural features of controller:

1. The contact structure adopts building block type, double row arrangement, compact structure and convenient assembly.

2. New materials, contact support, cam plate, panel and hand wheel are made of thermoplastic materials (polycarbonate, polystyrene), etc.

3. Small volume and light weight. 4. Light operating force. 5. Convenient maintenance for users. 6. Save non-ferrous metals.

7. Reduce machining workload.
