Description
The NR2-25G/2.5-4.0 thermal overload relay is a protective device designed to safeguard motors operating within a current range of 2.5 to 4.0 amperes. Built with a 3-phase bimetallic mechanism, it offers reliable overload and phase-loss protection for AC motor circuits up to 690V. The relay features adjustable current settings, temperature compensation, and both manual and automatic reset options, making it adaptable to various operating conditions. It includes a tripping indicator, test and stop buttons, and electrically isolated auxiliary contacts (1NO + 1NC) for control signaling.
