IEGS12-29736-1-V Circuit Protection

A circuit breaker, often abbreviated to CB, is an important safety device that is used in electrical systems. It functions as a switch for high current flow, preventing overload from damaging the circuits. IEGS12-29736-1-V is an example of type of circuit breaker. Before delving into the application field and working principle of IEGS12-29736-1-V, let us discuss circuit breakers in general.

Generally, circuit breakers are rated by their maximum voltage and current carrying capacity. Depending on their ratings, they can be used to protect appliances, electrical motors, low or high-voltage circuits, power tools and other equipment. A circuit breaker is an electromechanical device that will break an electrical circuit when it senses a current above the rated maximum. The breaker will either trip or break the circuit, preventing the current from travelling further and thus providing protection against overload. It is a much faster response to overcurrent than that of a fuse.

IEGS12-29736-1-V is a numerical control circuit breaker with three poles. It is rated up to 1,000A and 690V AC. This type of breaker is suitable for circuit protection in mainly industrial high power and high voltage applications, such as power distribution substations. It is designed to provide protection for over-currents, short circuits and ground-faults. It also includes built-in anti-residual current protection.

The working principle of IEGS12-29736-1-V relies on the three-pole rectifier. This ensures current and power handling accuracy and minimises the losses and resistive heating in the rectifier. The breaker utilizes a bimetal device to sense overcurrents. This bimetal expands and contracts rapidly when exposed to temperatures produced by an overcurrent. This causes the current carrying contacts to separate, thus disconnecting the circuit. This prevents any damage to the protected equipment.

Modern IEGS12-29736-1-V also include a trip indicator display system to indicate when a circuit breaker trips. This helps the user identify where the fault is located and whether it is the result of an overload or a short circuit. It also allows for quick and easy reset of the breaker when the fault has been resolved.

In conclusion, IEGS12-29736-1-V is a numerical control, three-pole circuit breaker with protection for overcurrents, short circuits and ground-faults. It is suitable for use in a wide range of industrial high power and high voltage applications. The breaker utilizes a bimetal device to sense overcurrents, causing the current carrying contacts to separate in order to break the circuit. Furthermore, it includes a trip indicator display system to indicate when a circuit breaker trips.
