Circuit Breaker
SYHF Electric has a core team of experts and technical backbones with rich industry experience and outstanding performance. The company's Circuit Breaker is an important electrical safety device, mainly used to prevent equipment damage or fire hazards caused by overcurrent or short circuit.
Its basic principle is to quickly interrupt the flow of current after the protection relay detects an electrical fault, thereby cutting off the source of the fault. Unlike fuses that can only be used once, circuit breakers can be reset and power restored manually or automatically after tripping, with the advantages of repeated use and convenient operation.
Circuit Breakers are widely used in power systems such as distribution boards and switch cabinets. They can be used as overload protection devices, and are often used as main switches to manually disconnect and connect electricity in a certain area, realizing effective management and safe control of power grid subsystems. Whether in household electricity, industrial loads, or in high voltage systems in large substations, circuit breakers play a key role in electrical protection.

Gas Load Break Switch
The SYHF high quality gas load break switch that uses SF6 gas as insulation and arc extinguishing medium is called SF6 gas load break switch. It can be used to switch load current and overload current, as well as to switch no-load circuits, no-load transformers, capacitors, and outdoor pole load circuit breakers. All three position load switches with connection, disconnection, and grounding functions have the characteristics of simple structure and low cost. But the load switch cannot disconnect the short-circuit current.
Medium Voltage Load Break Switch
SYHF durable Medium Voltage Load Break Switch is suitable for switching cable sectionalizers, transformers, and motor circuits in secondary distribution substations of power lines, transformers, and ring networks. It can be used in conjunction with DIN standard fuses to protect transformers. The ANSI version is used for metal enclosed switchgear, padded cabinets, mining, and capacitor switch applications.
Air Load Switch
SYHF durable Air Load Switch， Disconnector for 24kV 50Hz power system. The switch is installed indoors and can cooperate with manual and electric operating mechanisms. The switch can be used together with fuse and grounding switch. Adhering to the business tenet of "leading technology, quality first and win-win cooperation", the company strives for survival by quality and reputation by service, wholeheartedly serves the new and old customers, and feeds back the support and trust of all sectors of society.
Indoor Disconnector Switch
SYHF high quality Indoor disconnector switches are essential components in medium voltage power systems, used to isolate circuits during maintenance or faults. They operate under no load conditions, ensuring the visible and reliable disconnection of power sources.We strictly follow the IEC/GB standards for production, have type test reports, and have a complete production line and quality management system. Delivery is fast, come and cooperate with us!
Load Breaking Switch
Syhf high quality load breaking switch is a switch designed to turn on or off a specific current. This is achieved by adding equipment, which can improve the operating speed of the disconnector blade, add some type of equipment to change the arc phenomenon, and allow the safe interruption of arc when switching the load current. Disconnectors can be provided with equipment to provide limited load switching capability. Bow angle and whip spring actuators are typical at low voltage.
AC Load Breaker Switch
SYHF as a China suplier, who has his own factory,providing AC Load Breaker Switch is usually suitable for AC 50/60Hz, rated voltage 12kV power system. The product is designed for safety control circuits and complies with IEC60265 and GB/T11022 "General Technical Conditions for High Voltage Switchgear and Control Equipment". The product is a pollution-free product and is suitable for heavily polluted areas.
