Circuit Breakers

Circuit Breakers are vital components of industrial as well as home circuits, which help in protecting the circuit from any kind of overload and short circuit. Their primary function is to provide a short circuit protection and over current protection. They are also used in other applications such as motor protection, motor control, home and industrial automation, electromagnetic compatibility, arc-flash protection, etc. One of the most common Circuit Breakers used is UPL555-1208-2. This article will talk about the application fields and the working principle of this UPL555-1208-2 Circuit Breaker.

Application Field of UPL555-1208-2 Circuit Breaker

The UPL555-1208-2 Circuit Breaker is primarily used in the residential and commercial sectors to protect the circuit from high current and short circuits. It is also used in industrial applications such as motor protection, motor control, home and industrial automation, electromagnetic compatibility, arc-flash protection, etc. It has a wide range of applications in various areas, and is reliable and easy to install.

Working Principle of UPL555-1208-2 Circuit Breaker

The UPL555-1208-2 Circuit Breaker is a thermal-magnetic type circuit breaker. It works by sensing the current flow in a circuit and tripping when the current exceeds a given threshold. It also trips when there is a short circuit or overload in the circuit. The working principle of the UPL555-1208-2 Circuit Breaker is based on two main components: the thermal component and the magnetic component. The thermal component is the primary element that provides fast protection during short-circuits, while the magnetic element controls the maximum current allowed in the circuit. The thermal component works by using a heat-sensitive element, usually a bimetallic strip, which is heated up when a current passes through it. When the current is too high, the heat-sensitive element will expand, which will cause the circuit breaker to trip.The magnetic component works by sensing the current flow in the circuit and activating the tripping mechanism when the current exceeds a given threshold. The current is sensed by measuring the power dissipated in the coil of the breaker. When the current is too high, the magnetic force increases, which in turn activates the tripping mechanism and the breaker trips.

Conclusion

The UPL555-1208-2 Circuit Breaker is a reliable and cost-effective solution for protecting various kinds of electrical circuits. It helps to prevent overload and short circuit in the circuit, and ensures safety of the circuit from any kind of damage. Its advantages include its wide range of applications, its fast reaction time for short-circuits and its capability of being remotely operated.
