Circuit Breakers

A circuit breaker, commonly known as a CB, is an electrical device that acts as a switch to protect and isolate a circuit from a fault, overload or short-circuit.

When current flows over a circuit breaker’s pre-defined limit, it trips and switches off the circuit. Thus protecting the circuit from potential damage.  Circuit breakers come in many different varieties, sizes, and ratings.

The 209-2-1-51-2-8-20-H is a type of circuit breaker designed for use in three-phase electrical power distribution systems, distributed generation systems, industrial process control systems, and other industrial and commercial applications. It operates according to a preset current rating, and when that current rating is exceeded, the breaker trips and disables the power supply.

Application Field

The 209-2-1-51-2-8-20-H is primarily used in industrial and commercial applications that require heavy loads of electrical energy. It is designed for use with three-phase electric power systems, as well as with distributed generation systems, and can handle a wide range of loads. It can be used for new construction, as well as for retrofitting applications.

Working Principle

The 209-2-1-51-2-8-20-H circuit breaker works on a preset current rating. When the current surpasses this rating, the breaker trips and disables the power supply. It rapidly trips, thus protecting the circuit from overloading or short-circuiting.

The breaker also features a magnetic field sensor that detects and responds to changes in the current. This helps ensure that the breaker is engaging in an appropriate and responsive manner. It also ensures that the breaker will respond to changes in power demands in a timely fashion.

The 209-2-1-51-2-8-20-H also has a thermal device that can detect excessive temperature changes. This helps to ensure that the breaker will trip if overheating occurs. Overheating can be caused by a number of different factors, such as an overloaded circuit or a defective component. The thermal device prevents potential damage from occurring by ensuring that the breaker trips in a timely fashion.

The 209-2-1-51-2-8-20-H is designed to be reliable and easy to install. It features an internal fuse that is easy to replace if needed. It also has an overall slim design, allowing for easy installation into most types of panels. Furthermore, it can be used in a variety of applications, from industrial to commercial.

The 209-2-1-51-2-8-20-H is a reliable and easy to use circuit breaker designed for three-phase industrial and commercial applications. It works on a preset current rating, and will trip when that current rating is exceeded. It also features a magnetic field sensor, a thermal device, and an internal fuse for added reliability.
