219-3-2R-2911-30

Circuit breakers are electrical safety devices designed to protect electrical circuits from damage caused by overloads or short circuits. The 219-3-2R-2911-30 is a type of circuit breaker designed to automatically shut off power to a circuit if an overload or other fault condition is detected. In this article, we\'ll take a closer look at the 219-3-2R-2911-30 circuit breaker, including its application field and working principle.

Application Field

The 219-3-2R-2911-30 is a medium-voltage circuit breaker with an interrupting rating of 11kV. It is designed for use in commercial and industrial installations, including power plants, substations, and distribution systems. It is also suitable for use in installations with a high fault current, such as wind farms or other renewable energy sources. In addition, the 219-3-2R-2911-30 is suitable for use in installations with a higher power factor, such as power factor correction systems.

Design Features

The 219-3-2R-2911-30 circuit breaker has several design features that make it well-suited for use in demanding environments. It has a high-performance arc quencher, allowing for a fast fault response time. Its contact system is designed for long life and reliable operation. Its housing is made from rugged composite material for additional strength and durability. It also features an easy-to-read LED indicator light, allowing for quick diagnosis of faults.

Working Principle

The 219-3-2R-2911-30 circuit breaker is designed to protect electrical circuits from overloading and short circuiting. It works by measuring the voltage and current on the circuit and automatically switching the circuit off if it detects that either parameter has exceeded the specified threshold.When the voltage or current exceeds the threshold, the breaker trips and power to the circuit is shut off. The circuit breaker then automatically resets once the fault has been cleared, allowing power to be restored to the circuit.The 219-3-2R-2911-30 is designed to provide maximum safety and reliability in any application. Its design features make it well-suited for use in commercial and industrial installations. Its working principle ensures that electrical circuits are protected from damage caused by overloads or short circuits.
