Circuit Breakers

209-3-2599-373 is a type of circuit breaker. A circuit breaker is an electrical switch which is used to provide overload protection and also serve as a control switch.

Application Field

Circuit breakers are commonly used in residential, commercial and industrial installations, where they are used to provide protection to people from electric shock and protection to delicate electrical equipment from over-current and short-circuit damage. Circuit breakers provide a safeguard from electrical fires by preventing the flow of excessive current and providing fast and efficient switching action from incomings to outgoing lines.

In dwellings, circuit breakers are used to protect the electrical circuits running throughout walls, floors and ceilings. They provide protection from overload currents that may originate from a fault current, when equipment melts or if insulation between contacted parts fail. Circuit breakers can also be used to regulate the flow of current in certain conditions, such as when the current is too high or too low, and even when there is a power surge. In industrial applications, circuit breakers serve as a replacement for fuses and can be used to provide protection for electric motors, distribution transformers, generators, high-voltage components and other equipment that require greater protection.

Working Principle

The working principle of a circuit breaker is relatively simple. When the current through the breaker reaches its rated value, a solenoid or some other type of electromechanical device is activated to interrupt the current flow. The interruption is performed by rapidly separating the two contacts of the breaker. When the current drops below a certain threshold, the breaker will reset itself and reestablish the circuit.

The circuit breaker can be catered for for a variety of functions including overload protection, short-circuit protection, manual reset, automatic reset, indicator lights and others. The breaker will disrupt the flow of electricity once it reaches a certain value, and will then reset after a predetermined time. Different types of circuit breakers have different features depending on their purpose.

Circuit breakers are often used in a variety of installations such as homes, factories, hospitals, and other establishments. They provide a safe and reliable way to protect the circuit in which they are installed and also keep people and equipment protected from electrical fires.
