The CHINT NR2-25 12-18A thermal overload relay is designed to provide reliable protection for three-phase asynchronous motors against overload and phase failure. It features an adjustable current setting range from 12A to 18A and integrated temperature compensation to ensure stable performance under varying ambient conditions. The device is equipped with test and stop buttons, a trip indicator, and a selectable manual or automatic reset mode. It includes one normally open (NO) and one normally closed (NC) auxiliary contact, which are electrically separated for use in control circuits.
