Circuit breakers are one of the most important components in the electrical system, playing an important role in protecting both the health of people and the safety of electrical system. IELXK111-33850-1-V is a kind of circuit breaker, and its application field and working principle are also particularly important. In this article, we will analyze IELXK111-33850-1-V\'s application field and working principle in detail.

Application Field of IELXK111-33850-1-V

IELXK111-33850-1-V is suitable for circuit with rated voltage of 230V AC 50Hz or 120V DC, rated current 0.5A to 118A. It works reliably in various outdoor environment, like abnormal high humidity, high dust, high temperature and strong interference. Besides, it is also widely used in automated production line, connection and disconnection of electric appliances and the output of solar array string, etc. It can fulfill the protection requirement of the electric system and the circuit from over-current, overvoltage, short circuit and other abnormal situation. It is well known for its low energy consumption, high reliability, high breaking capacity, good heat dissipation, low leakage current and strong anti-interference.

Working Principle of IELXK111-33850-1-V

IELXK111-33850-1-V uses the principle of electromagnetic force to open or close the circuit. When the current flowing through the circuit exceeds the rated value, first it will activate a device called electromagnetic pull-in solenoid. The solenoid produces a very strong axial magnetic field that generates a high magnetic flux that attracts the movable contact piece of the breaker. When the movable contact piece reaches the rated closing position, it will create a short circuit, while the closing position of movable contact piece should be within the rated value, so that it can prevent the over-current in the circuit. When the over-current in the circuit surpasses the rated short circuit current and lasts more than a certain time, the movable contact piece will be separated from the fixed contact piece, so that the circuit breaker moves to the open position and the circuit is broken.

In addition, IELXK111-33850-1-V also has the following protection function: when the voltage across the circuit increases abnormally, it will send a signal to its control unit, which will actuate the opening or closing of the circuit breaker quickly.

In conclusion, IELXK111-33850-1-V has wide applications and reasonable working principle. It has various advantages like high reliability, high breaking capacity, good heat dissipation, low leakage current and strong anti-interference, providing strong protection for the electric system and the circuit.
