IEGHF66-32245-30 circuit breaker is mainly used in the distribution network of low-voltage system of enterprises and institutions to protect wires, distribution boxes, electrical appliances and other equipment from overload or short circuit damage or fire accidents. IEGHF66-32245-30 circuit breaker is suitable for AC50Hz, rated working voltage at 380V and rated operating current up to 32A.

The IEGHF66-32245-30 circuit breaker is composed of an arc extinguishing chamber, an operating mechanism, a fixed contact and a moving contact. When the load current exceeds the rated current, a phase disjunction line will automatically close. At this time, the phase disjunction line of the circuit breaker will fall off, and the arc board of the circuit breaker will be opened, thus the circuit will be automatically interrupted and the current will be cut off to protect the electrical equipment. After the fault is removed, the handling mechanism of the circuit breaker can restore the contact between the phase and the current. The mechanism of IEGHF66-32245-30 operating current is significantly less than that of the tripping current. It has the characteristics of sensitive opening, complete protection, long life and reliable performance.

A major advantage of the IEGHF66-32245-30 circuit breaker is the arc extinguishing chamber, which consists of a container with a built-in arc extinguishing chamber that is coated with a dielectric material. The dielectric material can effectively extinguish the arc generated in the fault, while ensuring the safety of personnel and equipment. In addition, a wire fault protection component is added to the IEGHF66-32245-30 circuit breaker, which has the function of wire fault protection.

The operating principle of IEGHF66-32245-30 circuit breaker is that when the power is on, the operating mechanism drives the fixed and moving contacts together, and the current passes through the circuit. When an overload or short circuit occurs in the circuit, the current increases significantly, which causes the current characteristics to exceed the operating current of the circuit breaker. Then the contacts are separated and the current is interrupted, which realizes the trip protection of the circuit. Finally, the operating mechanism can reset and restore the contact.

In summary, IEGHF66-32245-30 circuit breaker is a device that can automatically disconnect the circuit when the current is in excess of the rated current, thus effectively protecting the safety of electrical equipment. It has a built-in arc quenching chamber, which can effectively extinguish the arc generated during a fault, as well as a wire fault protection component to protect the circuit during wire faults. The operating principle of the circuit breaker is that when the current exceeds the rated current, the contact is separated and the current is interrupted.
