A circuit breaker is an effective electrical device used to protect an electrical circuit from damage caused by overload or short circuit. The term itself is derived from the fact that it is used to "break a circuit" - an interruption of the current flow. The model 8340-T120-K1T2-ALH126-10A circuit breaker is a thermal magnetic device. It has been designed to detect and isolate over-currents and short-circuits in distributed power systems.

The 8340-T120-K1T2-ALH126-10A circuit breaker provides excellent protection against current overload and short-circuits in power systems. It is designed for use in medium to high-voltage systems, and is often found in domestic, commercial, industrial and public power distribution networks. The function of the breaker is to protect the electricity supply from being overloaded and to prevent current from going through excessively high levels, which can cause permanent damage to other components of the system. The 8340-T120-K1T2-ALH126-10A circuit breaker has two different operating principles - thermal and magnetic.

The thermal principle, also known as the thermal-magnetic tripping mechanism, is based on the heating of the breaker contacts due to current overload, which is detected by the thermal element of the breaker. The thermal element monitors the temperature of the breaker contacts and trips the breaker if it gets too hot due to overloading. This helps to protect the system from short circuits and other forms of overloading, as it can quickly and safely de-energize the system when needed.

The magnetic principle, also known as the magnetic tripping mechanism, works by monitoring the magnetism of the magnetic trip bar, which is connected to the current carrying wire. If the current rises to a level whereby it exceeds the thresholds set by the circuit breaker, the magnetic force of the trip bar will cause the breaker to trip, thus preventing any further overloading. This function of the breaker is extremely useful in protecting from short-circuits which could otherwise cause irreparable damage.

The 8340-T120-K1T2-ALH126-10A circuit breaker provides an effective and reliable solution for various applications in power systems, including domestic, commercial, industrial and public networks. It is designed to detect and react to overcurrents and short circuits quickly and safely to protect the system from permanent damage or destruction. By combining thermal and magnetic principles of operation, the circuit breaker is able to detect and isolate hazardous situations quickly, securely and efficiently.
