The CHINT NR2-25-6 is a reliable thermal overload relay designed to provide effective overload and phase failure protection for three-phase AC motors in industrial control and automation systems. As part of the trusted CHINT NR2 thermal overload relay series, it offers adjustable current protection and dependable motor safeguarding for contactor-based motor starters.
This relay uses a three-phase bimetal thermal protection design with temperature compensation to provide stable operation under changing environmental conditions. The compact construction, integrated reset functions and diagnostic buttons make the NR2 series easy to install and maintain in industrial electrical panels.
With an adjustable current setting range of 4 A to 6 A and a rated insulation voltage of 690 V AC, the NR2-25-6 is suitable for protecting small to medium industrial motors used in pumps, conveyors, compressors and manufacturing equipment.
Thermal overload relays such as the CHINT NR2-25-6 protect electric motors by monitoring current levels and disconnecting the motor circuit when overload conditions occur. This helps reduce the risk of overheating, winding damage and unexpected equipment downtime.
The NR2 series is designed for industrial automation engineers and panel builders requiring dependable motor protection, straightforward installation and compatibility with modern contactor-based control systems.
