10131933-944ULF

10131933-944ULF is a signal intelligent single-phase leakage protection switch that can apply in single-phase two-wire system. It has the functions of Leakage protection, Short circuit protection, Overcurrent protection and Overvoltage protection. When there is a short circuit, impact current, inverse connection, overvoltage and other faults in the working system, the device will automatically and quickly disconnect the circuit to realize the requirements of safety protection.

This device is mainly composed of a circuit breaker, an integrated circuit, a current transformer, an indicator light and a tripper. The integrated circuit is responsible for receiving the voltage signal and current information from the line side, and then triggering the tripper to control the action of the circuit breaker in the protections of Overvoltage, Short circuit, Overcurrent, Leakage protection etc. The indicator light helps to diagnose if the device is working properly.

The 10131933-944ULF signal intelligent single-phase leakage protection switch is installed between the power supply and load, with the connection of the power supply, current transformer and load respectively. When the power supply is connected, the current transformer produces the secondary current signal proportional to the primary current. Then the current signal is transmitted to the input port of the integrated circuit, and compared with the preset value. If there is an overcurrent, overvoltage and other characteristics of the fault, the integrated circuit will trip the circuit breaker.

This protection switch is widely used in household wiring, building electric power, communications industry, fire protection industry and so on. It is a kind of protective device to protect the safety of the electricity, and has become an essential safety device for electrical appliances.

In summary, 10131933-944ULF signal intelligent single-phase leakage protection switch has a wide application field and performs excellent in the detection of overvoltage, overcurrent, leakage current, short circuit and other characteristics of fault. Its working principle is based on its main components, integrated circuit and tripper, working together to detect the electrical parameters changes and generate a quick trip signal to the circuit breaker.
