Circuit breakers are designed to protect electrical systems from damage
As of 2025, there are 76 circuit breaker manufacturers. Circuit breakers are essential safety devices designed to protect electrical systems and users from damage and harm. They are installed in distribution boards and act as a main switch to manually disconnect and connect electrical power.
Circuit breakers are designed to detect a fault or overload in the electrical current and interrupt the power supply to prevent damage to outlets and equipment. This is achieved by using either a bimetallic strip or an electromagnet. When the current passes through the bimetallic strip, it heats up and bends, causing the circuit to break. With an electromagnet, the current creates a magnetic field, which activates a spring to break the circuit.
There are various types of circuit breakers, including small mains and low-voltage circuit breakers, which are commonly used in homes to protect appliances and electrical grids. These typically use the heating effects of electric current to detect a fault. Larger circuit breakers for high voltages are usually arranged with protective relay pilot devices to sense a fault and operate the opening mechanism. These require a separate power source, such as a battery.
Ground fault circuit interrupters (GFCIs) are a type of breaker designed to protect people from electrical shock. They constantly monitor the current in a circuit's neutral and hot wires. When a person accidentally touches a hot wire, for instance, the GFCI breaks the circuit, preventing electrocution. Arc fault circuit interrupters (AFCIs) are another type of breaker that electronically monitors the power grid for arc faults, which can lead to extreme heat in wiring and fire hazards.
Circuit breakers are also used in industrial and electric power systems, with power circuit breakers and medium- to high-voltage circuit breakers designed to ANSI or IEEE standards. These breakers are typically controlled by separate protective relay systems, allowing for adjustable tripping currents and complex protection schemes. Overall, circuit breakers play a crucial role in ensuring the safe operation of electrical systems and protecting users from harm.

Breakers are also known as circuit breakers or electrical panels
Breakers, also known as electrical panels or circuit breakers, are essential safety devices in any home electrical system. They are designed to protect an electrical circuit from damage caused by a current in excess of what the equipment can safely handle. Its basic function is to interrupt the current flow to protect equipment and prevent fires.
Circuit breakers are commonly installed in distribution boards and are made in varying current ratings. They can be used to protect low-current circuits or individual appliances, and they can also be used to protect high-voltage circuits that power an entire city. The three main types of circuit breakers are standard, GFCI, and AFCI.
GFCI stands for Ground Fault Circuit Interrupter, which is designed to protect people from electrical shock. AFCI stands for Arc Fault Circuit Interrupter, which electronically monitors the home's power grid for arc faults that older breakers might miss. These arc faults can lead to extreme heat in wiring and fire hazards.
Circuit breakers can be reset either manually or automatically, unlike fuses which must be replaced once they have operated. They are typically installed indoors but can also be installed outdoors depending on their specifications. When an overcurrent or leakage current occurs, the power supply is cut off to prevent fires or electric shocks.
There are a variety of circuit breaker manufacturers, including Paneltronics, Leviton Manufacturing Co., Inc., and Ace Hardware.
