Circuit Breakers - 4411.0018 Application Field and Working Principle

Circuit Breakers are key components of any electrical system, broadly defined as a device designed to break an electrical current flow when an overload or short circuit has occurred in the circuit it is protecting. Circuit Breakers are divided into five distinct categories based on their specific applications and functions.The 4411.0018 type of circuit breaker is a medium voltage sampling circuit breaker designed specifically for use in industrial automation applications. This robust circuit breaker has a large load capacity and is available in a range of contact ratings with a wide range of current and voltage ratings. It can be used to protect power systems from both overloads and short circuits. The 4411.0018 circuit breaker works using a three contact system in order to detect overloads and short circuits. The three contacts consist of the two contacts which make the load connection, and the third contact which is located between them. This is the measurement contact, composed of a wound coil, which is located in the phase current and corresponds to the current of the phase. It operates in the same way as a voltage detector circuit. When an overload or short circuit occurs, the coil becomes magnetized and the magnetic field generated by the coil causes it to attract the two load contacts and thus interrupt the current flow. This is done by using a mechanical lever connected to the contacts. The lever is moved when the coil becomes energized and pushes against the contacts in order to open the circuit.In addition to the overload and short circuit protection, the 4411.0018 type of circuit breaker also provides isolation protection and has a pushbutton reset feature. This provides convenience in resetting the circuit breakers after use, without the need to turn off the power supply.Overall, the 4411.0018 type of circuit breaker is an ideal choice for industrial automation applications due to its robust design, high current and voltage ratings, and its reliable operation in the detection and interruption of overloads and short circuits. Its ability to provide isolation protection, as well as its convenient pushbutton reset feature makes it a highly efficient and cost-effective choice for electrical systems in a wide variety of industries.
