?? SYSG series load isolation switch (hereinafter referred to as switch) for AC 50Hz, rated current of 660V rated current to 3200A, for infrequent making and breaking circuit. The modular design structure, with flexible combination of using unsaturated polyester glass fiber reinforced plastic (DMC), manufactured housing, has a high dielectric properties, protection and reliable operation of security. The operating mechanism is spring energy storage, instantaneous release acceleration mechanism, instant-on and breaking the double-break contact structure. Independent of the speed of the operating handle, greatly increasing the electrical performance and mechanical properties. Switch is widely used in construction, electricity, petroleum, chemical and other industries and distribution systems and automation systems. ?? Switch handsome in appearance, novel, simple, small size, full-featured, is the ideal choice for similar products. ?? A variety of structures and mode of operation, there is direct observation of contact-off state of the window, there is the cabinet, operation outside the cabinet, front, side operation, there are rear connection. ?? Spring energy is released instantaneously accelerated mechanism to achieve a fast turn-breaking cargo (13.8 m / s), regardless of the operating handle speed, greatly improving the ability of arc lights. ?? Advanced horizontal pull points and technology, a unique parallel double break contacts Shuangqiaoshan type spring sheet structure, extend switch life; using a switch life of more than 8000 times. ?? In the "O" position, which can handle with three locking lock, to prevent misuse.
