China DC Circuit Breaker Manufacturers and Suppliers

CHYT Electric is a professional factory that develops and produces low-voltage electrical equipment and electrical components. We have independently developed and produced products such as photovoltaic dc circuit breaker, photovoltaic AC/DC combiner boxes, distribution cabinets, large photovoltaic grid connected cabinets, grid connected boxes, and photovoltaic lightning protection. It can meet the needs of various new energy grid connected distribution applications, with easy installation, strong reliability, and complete qualifications. The company also has direct stores and a large number of agents on various online platforms, and has entered overseas markets.

CHYT dc circuit breaker is designed to provide overcurrent protection in electrical appliances or equipment that have already provided or do not require branch circuit protection. The device is designed for direct current (DC) control circuit applications. The rated working voltage of dc circuit breaker can be as high as DC 1000V. It adopts a special arc extinguishing and current limiting system, which can quickly cut off the fault current of the DC distribution system, protecting the important component in the solar photovoltaic power generation system - the photovoltaic module - from the harm of high DC reverse current and AC feedback current caused by inverter faults, ensuring the reliable operation of the solar photovoltaic power generation system.

CHYT dc circuit breaker has excellent current limiting performance, which can accurately protect relay protection and automatic devices from overload, short circuit and other fault hazards. The dc circuit breaker has the advantages of current limiting and arc extinguishing capabilities. After a large number of comprehensive scientific experiments, it can achieve fully selective protection between the main (sub) screen, protection screen, and relay screen levels in DC systems below 3000Ah. The working principle of AC short circuit is similar, but it is only used in different occasions. And commonly referred to as switches, they are divided into operating mechanisms, arc extinguishing systems, contact systems (main circuit), and tripping single units (also divided into mechanical thermal magnetic, electronic, and other types).
