Effektbryter

Effektbryter, also known as a circuit breaker, is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its primary function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and needs to be replaced, a circuit breaker can be reset manually after tripping, making it a more convenient and reusable solution.

Circuit breakers work by sensing the electrical current flowing through the circuit. When the current exceeds a safe level, typically due to an overload or short circuit, the breaker trips, opening the circuit and stopping the flow of electricity. This action prevents overheating and potential fire hazards, as well as damage to connected equipment.

There are different types of circuit breakers, including thermal-magnetic, electronic, and solid-state breakers. Thermal-magnetic breakers use a combination of thermal and magnetic elements to detect faults, while electronic breakers rely on electronic sensors and control circuits. Solid-state breakers use semiconductor devices to interrupt the current flow.

Circuit breakers are widely used in residential, commercial, and industrial settings to ensure the safety and reliability of electrical systems. They are an essential component in electrical distribution systems, helping to maintain power quality and minimize the risk of electrical fires and equipment damage. Regular maintenance and testing of circuit breakers are crucial to ensure their proper functioning and the overall safety of the electrical system.
