A circuit breaker is a mechanical device designed to protect an electrical circuit from damage caused by overload or short circuit. 3120-F521-N7T1-W01A-12A is a high-performance circuit breaker manufactured by a reliable manufacturer. This circuit breaker features a designed switching power of 20A and high-end protection of up to 8.4 kA, making it suitable for a wide range of industrial applications.

Application Field

3120-F521-N7T1-W01A-12A is suitable for use in a variety of industrial applications, such as instrumentation and control systems, machine tool automation, process control systems, robotics, power systems, security applications, and others. In addition, this circuit breaker can also be used to protect moulded case circuit breakers, low-voltage power circuit breakers, mini circuit breakers, and other related equipment, as well as to ensure safety in various situations.

Working Principle

The 3120-F521-N7T1-W01A-12A circuit breaker works according to the principles of electrical circuit protection. When the current overloads or shorts, the circuit breaker will open the circuit and prevent damage. This is done by the use of two components: a contact plate and an arc plate. The contact plate is a movable plate made of metal and has a magnetic force that allows it to open and close, while the arc plate is a stationary plate, which is also made of metal, and acts as a shield to suppress the arc when the contact plate opens or closes. When the current increases beyond the set limit, the magnetic force on the contact plate increases, causing the plate to move and break the contact with the arc plate. This allows the current to be interrupted and the circuit to be protected.

The 3120-F521-N7T1-W01A-12A circuit breaker is designed to provide reliable protection, while also providing an up-to-date design and modern automation features. This makes it suitable for a variety of applications, including both commercial and industrial applications. In addition, the circuit breaker is designed to be both easy to install and use, making it an ideal choice for any project.
