Circuit breakers are devices designed to protect electrical circuits from damage caused by abnormal or excessive current. The 1278760000 application field and working principle of circuit breakers can be grouped into two main categories.

Thermal-Magnetic Circuit Breakers: Thermal-Magnetic circuit breakers are the most common type of circuit breaker and provide both thermal and magnetic protection. Thermal protection prevents overheating due to excessive current, while magnetic protection offers short-circuit protection. These circuit breakers are activated by currents that exceed the breaker\'s pre-set trip value. Once the preset value is exceeded, the bimetallic element inside the breaker expands due to the heated current, thus causing the circuit breaker to trip and disconnect the circuit.

Residual Current Circuit Breakers (RCCBs): Residual current circuit breakers are designed to protect humans from electric shock by detecting and disconnecting circuits when an electrical fault is detected. These circuit breakers are triggered by changes in current that exceed predetermined levels. This is done by using two coils within the breaker – a residual current coil detects alternating current and a safety coil detects direct currents. If an imbalance is detected by either coil, it will result in an automatic disconnect of the circuit, which prevents human contact with live electrical parts.

Arc-Fault Circuit Breakers (AFCBs): Arc-Fault circuit breakers (AFCB) are designed to detect and disconnect arcs that occur when electricity is short-circuited or a circuit overloads. This type of breaker detects faults by monitoring current trends that indicate arcing and instantly disengage the circuit as soon as arcing is detected. AFCBs protect against both overloads and short-circuits and are mandatory in many electrical installations.

High Voltage Circuit Breakers: High voltage circuit breakers are designed to protect electrical circuits from excessive currents that can occur in applications requiring high voltages. These circuit breakers are typically air-break types because air is the most effective and reliable medium for interrupting high voltage arcs. Air break circuit breakers use compressed air to interrupthigh voltage arcs, and their operation is based on the principle of a rapidly moving arc being interrupted by using a blast of high-pressure air.

Surge Protectors: Surge protectors are devices installed to protect electrical circuits from voltage spikes that can occur due to lighting, electrical shorts and other sources. These protectors are typically installed at the point of entry of an electrical circuit and use a combination of electrical and electronic components to divert excessive voltage to ground, thus preventing the circuit from experiencing damage.

The 1278760000 application field and working principle of circuit breakers are varied and important to understand in order to select the right breaker for a specific application. Selecting the wrong type or size of breaker can result in equipment damage, injury and even death. It is important to consult knowledgeable technicians when selecting a circuit breaker so that a suitable one can be chosen that meets all safety and operational requirements of the application.
