Product Description

As the core component of circuit conversion, it can not only realize the switching of conventional electrical control lines, but also directly start control of small and medium power motors, reversible operation switching and multi-speed variable speed adjustment, especially suitable for the working environment that needs to change the running state frequently.In structural design, LW5 switch adopts double-break bridge contact system, equipped with arc extinguishing device, small contact resistance and excellent breaking ability. Its protection grade reaches IP55, which can adapt to wet and dusty industrial environment. By changing the Angle combination of the CAM mechanism, the preset of up to 6 different control programs can be realized to meet the different control requirements of machine tool equipment, conveying machinery, lifting equipment, etc. The product conforms to GB14048.3 standard, obtained CCC compulsory certification, has short circuit protection function, and can realize overload protection when supporting thermal relay.
