Circuit Breakers are commonly used in homes, offices, and factories. They are designed to protect electrical equipment from overloading and short circuiting. The IEGF66-1-72-10.0-A-21-V Circuit Breaker is a type of circuit breaker with a specific application field and working principle.

The IEGF66-1-72-10.0-A-21-V Circuit Breaker is designed for applications in the medium voltage range. The rated insulation voltage is 10kV, the rated frequency is 50Hz, and the rated current is 72A. It can be used on three-phase power systems and in places where there is an arc suppression coil or magnetic release. Additionally, it is equipped with a low magnetic latching mechanism. The Circuit Breaker has an operating temperature range of -60 to + 60 degrees Celsius.

The working principle of the IEGF66-1-72-10.0-A-21-V Circuit Breaker is based on magnetic circuit breaking. When the power supply exceeds the rated current, the magnetic latching mechanism is triggered and the contacts in the breaker are separated, breaking the circuit. The magnetic field generated by the electric current creates a magnetic force on the moving contact arm, causing it to open the contacts and shut off the power. This action protects the circuit from further damage.

The IEGF66-1-72-10.0-A-21-V Circuit Breaker is a reliable and durable device and is suitable for various applications. It has been tested and certified by International Electrotechnical Commission’s (IEC) Standards. This circuit breaker is suitable for use in factories, homes, office buildings, power systems, and other places where a medium voltage needs to be protected.

In conclusion, the IEGF66-1-72-10.0-A-21-V Circuit Breaker is a medium voltage-resistant circuit breaker with a magnetic circuit-breaking mechanism. It can protect circuits from damage due to overloading or short circuiting. It has been tested and certified according to IEC Standards and is suitable for use in residential, commercial, and industrial applications.
