Circuit breakers are essential components in the electrical industry, as they are essential in energy transmission and distribution networks. The IEL1-33090-2-V is a typical type of circuit breaker with a wide range of applications and working principle.

The IEL1-33090-2-V is suitable for use in powerlines, distribution systems, and centres with a rated current up to 630A, as well as for control of DC currents up to 20A. It also has a wide of working voltages ranging from 6kV to 18kV. Those features make it suitable for a variety of applications, from residential to industrial. Furthermore, the breaker is equipped with an independent thermal and magnetic operation in addition to a mechanical trigger designed for instantaneous and delayed current operations.

The working principle of the IEL1-33090-2-V circuit breaker is actually quite simple. The breaker is designed to be sensitive to both thermal and magnetic energy and to respond appropriately when the current is beyond the set limit. When the current is too high, the thermal switch acts first and causes the current to trip. After the current has tripped, the magnetic switch will kick in and prevent the current from surging again until the thermal overload has cooled down enough. The thermal overload has a built-in reset button and a red LED indicator to indicate it has tripped, while the magnetic switch has a blue LED to indicate the current has been tripped due to a short. This process assures that the current is kept at safe levels for the installation.

The IEL1-33090-2-V is a reliable and durable circuit breaker with a wide range of applications and working principle. It is designed to be sensitive to pull and temperature changes and can respond quickly and accurately when excessive current is detected. The simple working principle adds to its versatility, making it suitable for both residential and industrial applications. Furthermore, it is equipped with a thermal overload and magnetic switch that cooperate to offer reliable protection against excessive current.
