Core Product Advantages and Features
Current adjustment range 17-22A
The trip setting value can be precisely adjusted according to the motor's rated current to provide appropriate overload protection.
Screw terminal design
Both the main circuit and the auxiliary circuit use screw terminals, which facilitates wiring construction and on-site maintenance.
Independent and separate installation
It does not need to be directly mounted on the contactor body; it can be flexibly installed in an independent position according to the control panel configuration.
Class 10 Breakthrough Level
It meets the standard motor overload protection tripping characteristics, reducing the risk of motor damage due to overheating.
