description The invention relates to a low-voltage circuit chopper with quick activate function. Wherein, it comprises frame and handle; said frame has operator, arc extinguish system, electromagnetic detaching system, relative movable and stable contactors; the invention is characterized in that there is an activator between electromagnetic detaching system and operator; said activator is axially connected to the frame, with the first rod opposite to the iron core of electromagnetic detaching system and the second rod opposite to the detaching rod of operator; the rotation arm of first rod is higher than the one of second rod; the pushing force of iron core is amplified by the lever of activator, to push the detaching rod to trip, therefore, the movable and stable contactors of chopper can be cut off reliably; and since the activator is between the detaching system and operator, it will not increase the volume of chopper.
