Description

technical field [0001] The invention relates to the technical field of motor protection controllers, in particular to an arc extinguishing shell material of a motor protection controller. Background technique [0002] The motor protection controller is mainly used to protect various motors in high-voltage working conditions, and to protect the hazards caused by faults such as short circuit, overload, phase failure, and unbalance of the motor. [0003] In the prior art, the motor protection controller is often in a high-voltage working environment, and is easily broken down by a high-voltage arc, resulting in damage to electronic components inside the protection controller. Contents of the invention [0004] According to the deficiencies of the prior art, the invention provides an arc extinguishing shell material for a motor protection controller. [0005] The present invention is achieved in this way, an arc extinguishing shell material for a motor protection controller, ...
