LK17 series master controllerDetailed product description：

The LK17 series is a non adjustable master controller that adopts the IEC standard. It has an advanced and reasonable structure, reliable operation, and easy operation. Compared with LK1 products, it reduces volume and weight by two-thirds, and increases electrical and mechanical life by 2-3 times. It has high mechanical performance. The contact of this product has a double break point, bridge structure, and strong arc extinguishing ability. The DC contains permanent magnet blocks for arc extinguishing. So the installation, use, and maintenance of this controller are extremely convenient, making it an ideal replacement product.  
Purpose:

LK17 series master controller, with a specified heating current of 10A, suitable for AC 50HZ, 380V and below, and DC 220V and below. Used for frequent switching of control circuits in transmission.
technical parameters

（1） The mechanical lifespan of the controller shall not be less than 3 million cycles, and the electrical lifespan shall not be less than 1 million cycles.
（2） The number of contacts in the controller is 2-12, and the left and right positions are 1-6.
（3） According to the different requirements of the controlled circuit, the master controller creates various working charts.
（4） The contact connection and disconnection capability of the controller meets the requirements of AC AC-11 and DC DC-11.

According to the different requirements of the circuit, the controller is made into various contacts, and the working chart is as follows:


Usage and maintenance
1. Equipped with terminal blocks for easy wiring, the arc extinguishing chamber adopts a double break bridge structure. Therefore, the electrical and mechanical lifespan is several times longer than that of old products.  
2. Maintenance is extremely convenient. No need for special tools. Long term use, if the current contact opening distance is less than 3 millimeters, the contact should be replaced in a timely manner, and attention should be paid to AC and DC.  
3. When using and maintaining on site, attention should be paid to safety and live working is strictly prohibited. When carrying out live work, safety equipment and protective gear should be worn, and someone should supervise to prevent accidents from occurring.  
4. When placing an order, the model of the controller must be marked as AC (J) or DC (Z).
