209-1-1-52-2-2-40

A circuit breaker is a device used to protect an electronic circuit from damage caused by an overload or short circuit. It is an automatic device that opens an electrical circuit when an overload or short circuit occurs. The 209-1-1-52-2-2-40 circuit breaker is a type of three-phase circuit breaker designed for use in medium voltage power distribution applications.The 209-1-1-52-2-2-40 circuit breaker is designed for safe and reliable protection against overloads, short circuits and ground faults. The breaker is available in both air and vacuum operation and can be used in systems ranging from 2.3kV to 25.8kV. The breaker has a range of features and accessories, including arc flash protection, remote control and features to minimize maintenance.The 209-1-1-52-2-2-40 circuit breaker is based on the principle of arc quenching. When an overload or short circuit occurs, the contacts within the breaker open, creating an arc. The arc is controlled by an arc chute, which consists of a series of plates, which contain either air or a vacuum.The arc between the contacts is extinguished when the air or vacuum within the arc chute increases in pressure due to the arc’s energy. This increases the pressure in the arc chute and forces the arc to be extinguished. After the fault has been cleared, the breaker automatically resumes operation.The 209-1-1-52-2-2-40 circuit breaker is designed to be highly reliable, with a wide range of safety features including arc flash protection, arc chute monitoring and breaker lockout. It is designed to provide protection to both personnel and equipment, and is capable of interrupting large short circuit currents of up to 100,000A.The 209-1-1-52-2-2-40 circuit breaker is a reliable and safe device that is suitable for use in a wide range of medium voltage power distribution applications. It is a reliable and economical option for circuit breaker protection and is easy to install and maintain.
