IELR111-1-61-7.50-01-V Application Field and Working PrincipleCircuit breakers are electrical devices used to protect electrical circuits from overloads or short circuits. They interrupt the flow of electricity when the current reaches a certain level. In this way, they prevent damage to the electrical system, as well as preventing fires caused by overheated wires. The IELR111-1-61-7.50-01-V is a type of circuit breaker with a wide range of applications, and a simple, efficient working principle. The IELR111-1-61-7.50-01-V Circuit Breaker is designed for three-phase voltage systems of up to 7.5 kV. It is commonly used in industrial applications to provide overload and short circuit protection, as well as preventing overload of equipment that could potentially cause fires. The IELR111-1-61-7.50-01-V has a range of features such as a control logic panel, temperature compensation, and an adjustable tripping-delay for protection of motors. It also features an arc quenching system to provide protection during arc faults and make switch control easier. The IELR111-1-61-7.50-01-V works on the principle of current transformer symmetrical components. Inside the circuit breaker, there are two current transformers, located on the main bus. These transformers measure the current passing through the main bus and convert it into two voltage signals, referred to as the "zero" and "positive" components.The circuit breaker also has a controller, which is responsible for comparing the two signals and then tripping the breaker if the current exceeds a predetermined level. The controller also monitors other parameters, such as the power factor, in order to provide a more accurate trip point. At the same time, the circuit breaker also has a short-circuit tripping system, which trips the breaker if the current rise rate reaches a certain level. This prevents dangerous overloads of the system, where the current could become too high too quickly and cause equipment failure or damage.The IELR111-1-61-7.50-01-V is a reliable, robust circuit breaker that is suitable for a wide range of applications. It has an adjustable trip point, and its simple working principle allows it to provide reliable overload protection for sensitive electrical equipment.
