Circuit breakers protect an electrical circuit from damage caused by overload or short circuit. Basically, it is a switch that senses the flow of electric current and opens the circuit if the current reaches a certain level, thus protecting the circuit from overload or short circuit. Power surge protection is one of the main functions of circuit breakers. There are many types of circuit breakers that serve different applications, with varying features. One such type is the IEG11-22276-4-V (Vacuum) circuit breaker.

The IEG11-22276-4-V is a medium-voltage circuit breaker designed to protect and control electrical systems with voltages up to 25kV. This type of circuit breaker is mainly used in applications with high short-time making and breaking capabilities, as well as a wide range of test currents. It is ideal for feeder protection and motor protection in power transformers, distribution, transmission, and industrial applications.

The IEG11-22276-4-V is a three-pole, air insulation circuit breaker that meets the requirements of IEC 62271-100. This type of circuit breaker uses a vacuum interrupter for superior performance. The vacuum interrupter is a sealed container that contains a high vacuum and reduces contact erosion, which extends the life of the breaker. The vacuum interrupter also provides a high dielectric strength and a low contact resistance, making it ideal for applications with high fault levels.

This type of circuit breaker is equipped with a storing-type operating mechanism and has the capability to perform operations like make and break, open shutter, close shutter, and lock-off. It has four switch positions - off, on, half-on, and test. As it is a storing-type circuit breaker, an internal spring mechanism is provided to release the switch contacts.

The IEG11-22276-4-V also includes over current protection, with a thermal-magnetic trip unit. This trip unit senses over currents and trips the circuit breaker to cut off the power. The trip unit has a built-in time delay function to protect against transient and momentary over currents. It is also able to detect short-circuits and will disconnect the circuit when a short-circuit is detected.

The IEG11-22276-4-V circuit breaker has been designed to meet stringent safety and performance standards and is certified by numerous international regulatory organizations. It has all the necessary certifications required for use in a variety of environments, including hazardous locations. It can be used in a wide range of applications, including motor protection, distribution, transmission, and industrial applications.

In summary, the IEG11-22276-4-V is a medium voltage circuit breaker designed to protect and control electrical systems with voltages up to 25kV. It is equipped with a storing-type operating mechanism and has four switch positions - off, on, half-on, and test. It also includes over current protection, with a thermal-magnetic trip unit and a built-in time delay function. The breaker is certified by various international regulatory bodies and is suitable for a wide range of applications.
