1DU30L circuit breakers, also called high-speed current limiting circuit breakers, are capable of limiting the magnitude of a high-frequency surge current and have rapid trip characteristics. It is widely applied in the protection of electronic equipments such as high-power UPS systems, wind and solar energy systems, server and electricity distribution systems, electric vehicles, power systems, and power supply equipment. A 1DU30L circuit breaker effectively prevent short circuits, short-term over-currents, long-term over-currents and continuous currents of low frequencies, as well as high-frequency and short-circuits, lighting and electric arc faults such as electric arcs that occur in the system and electric shock.

The working principle and structure of a 1DU30L circuit breaker is quite simple but highly effective. It consists of a main breaker, a thermal overload relay, a contact switch and a ground fault detector. The main breaker and the thermal overload relay are connected in series, and the contact switch is connected in parallel. The main breaker is responsible for breaking and making the circuit to control the on/off power state. The thermal overload relay is used to detect the temperature of the breaker so that the circuit does not overheat. The contact switch is the actual switch for opening and closing the circuit. The ground fault detector is used to detect any faults in the circuit, such as ground faults. If a fault is detected, the breaker will immediately trip and open the circuit.

1DU30L circuit breakers provide excellent protection to a wide range of electric systems. They are used in various industrial and commercial settings. It is designed to be able to quickly and reliably detect any fault in the system, and then to rapidly disconnect power, preventing further damage or injury. 1DU30L circuit breakers are also designed to be highly efficient and cost-effective. They can be used in a variety of settings and circumstances, making them one of the most versatile and cost-effective solutions available on the market.

Overall, 1DU30L circuit breakers are an invaluable tool for protecting electric systems from potential faults and damages. They provide an efficient and cost-effective way to ensure safe operation of equipment and provide protection from electrical hazards. They are used by a variety of industries and have proven to be an invaluable asset to the smooth and safe operation of systems around the world.
