What is PCB circuit breaker & with type?

 A PCB (printed circuit board) circuit breaker is a type of electrical switch that is designed to protect an electrical circuit from damage caused by overloading or short-circuiting. The circuit breaker is typically installed on a PCB, which is a flat board made of insulating material that contains a pattern of conductive pathways used to connect electronic components. The circuit breaker is connected to the PCB and can be triggered by a variety of sensors or devices that detect an overcurrent or short circuit condition. When triggered, the circuit breaker interrupts the flow of electricity to the circuit, preventing damage to the components and potentially saving lives.

PCB circuit breaker & with type?

Circuit breaker is a type of electrical switch that is designed to protect an electrical circuit from damage caused by excess current, typically resulting from an overload or short circuit. There are several different types of circuit breaker, including thermal, magnetic, and solid state. Thermal circuit breakers use a bimetallic strip that heats up and bends when too much current flows through the circuit, while magnetic circuit breakers use an electromagnet to open the circuit when too much current is detected. Solid state circuit breakers use electronic components to detect and interrupt an overcurrent condition.

Circuit Breaker

A circuit breaker is an electrical switch that automatically interrupts the flow of electricity in a circuit in the event of an overload or short circuit. It is designed to protect electrical equipment and wiring from damage due to excessive current. Circuit breakers can be found in homes, businesses, and industrial settings and come in a variety of sizes and types, including: Miniature Circuit Breaker (MCB): used to protect low voltage circuits and are typically found in homes. Molded Case Circuit Breaker (MCCB): used to protect medium voltage circuits and are commonly found in commercial and industrial settings. Air Circuit Breaker (ACB): used to protect high voltage circuits and are typically found in power distribution systems. Circuit breakers are typically controlled by a tripping mechanism, which senses when the current in a circuit exceeds a certain threshold and interrupts the flow of electricity. Circuit breakers can be manual or automatic, manual breakers need manual resetting after the trip, while automatic breakers can reset itself after the overcurrent is removed.

Including Thermal

Thermal circuit breakers use a bimetallic strip that heats up and bends when too much current flows through the circuit, causing the circuit breaker to trip and interrupt the flow of electricity. The bimetallic strip is made of two different metals with different thermal expansion coefficients, which causes the strip to bend when heated. The bending of the strip causes a mechanical mechanism to trip, opening the circuit. Thermal circuit breakers are typically found in low-voltage applications, such as household appliances and electrical tools. They are a common type of overcurrent protection and can be used as a standalone device or as a component in a larger electrical system.

Magnetic

Magnetic circuit breakers use an electromagnet to open the circuit when too much current is detected. They work by using the principle of electromagnetic induction, where a current flowing through a wire creates a magnetic field around the wire. When the current flowing through the circuit exceeds the breaker's rating, the magnetic field becomes strong enough to trip the breaker, which interrupts the flow of electricity. The electromagnet is typically made of a coil of wire that surrounds a metal core. When the current flowing through the coil exceeds the breaker's rating, the magnetic field created by the coil becomes strong enough to attract the metal core, which causes a mechanical mechanism to trip and open the circuit. The magnetic circuit breaker is usually found in devices that require protection from short circuits and overcurrents. They are often used in devices with high inrush current, such as electric motors, and devices that draw high current for short periods of time, such as air conditioners and refrigerators.

Solid State

Solid state circuit breakers use electronic components to detect and interrupt an overcurrent condition. Instead of using a mechanical mechanism to trip the breaker, solid state circuit breakers use electronic devices such as diodes, transistors and thyristors to control the flow of electricity. They are also known as electronic circuit breakers. In solid state circuit breaker, a sensing circuit monitors the current flowing through the circuit and compares it to a set point or threshold. When the current exceeds the set point, the sensing circuit sends a signal to the electronic switching device (e.g. thyristor) to quickly open the circuit, interrupting the flow of electricity. Solid state circuit breakers are more reliable and efficient than mechanical circuit breakers, and they have faster trip times and smaller size. They are typically found in high-tech applications such as renewable energy systems, industrial control systems, and medical equipment. They are also useful for protection of sensitive electronic equipment.
