The 8340-G211-K3E1-A4H131D-1A circuit breaker represents an important line of power circuit breakers. These high-performance circuit breakers can safely and reliably detect and cut off abnormal circuits, protecting the safety of electric equipment and personnel. They are widely used in power plants, substations, industrial and mining enterprises, and residential distribution systems.

The 8340-G211-K3E1-A4H131D-1A circuit breaker is mainly used in three-phase alternating current circuits with a rated voltage of 420V AC and a rated frequency of 50Hz. The rated current of the switch is 10A, the rated short-circuit breaking capacity is 14000A, and the rated short-circuit forced breaking capacity is 86000A.

The main functions of the 8340-G211-K3E1-A4H131D-1A circuit breaker are overcurrent protection, short circuit protection, and power failure protection. In addition, the switch can also be equipped with various accessories, such as trip indicator, auxiliary contact, etc., to provide more functions.

The working principle of the 8340-G211-K3E1-A4H131D-1A circuit breaker is simple. When the current passing through the circuit breaker reaches or exceeds the overcurrent protection value, the bimetallic sheet in the circuit breaker bends and drives the switch contact in the circuit breaker to trip to cut off the current. The electric energy accumulated in the system is discharged in the form of arc, and the switch contact levers in the circuit breaker are closed again under the action of spring force.

The 8340-G211-K3E1-A4H131D-1A circuit breaker features good electrical insulation performance, fast response characteristics, and reliable operation. The power plant system, electrical distribution system and other places using the circuit breaker can effectively protect the equipment and personnel from damage caused by overload, short circuit, and power failure.
