CHINT NR2-25-10 thermal overload relay with a 6.00–10.00 A adjustable current range designed for three-phase AC motor overload and phase-loss protection.
£26.19
The CHINT NR2-25-10 is a dependable thermal overload relay designed to protect three-phase AC motors against overload and phase-loss conditions in industrial motor control applications. As part of the proven CHINT NR2 thermal overload relay series, it provides adjustable motor protection and reliable operation for electrical control systems.
This overload relay uses thermal bimetal protection technology to monitor motor current and trip the control circuit when sustained overload conditions occur. The NR2 series is designed for simple integration with CHINT contactors, providing an effective solution for motor starters, automation equipment and industrial machinery.
With an adjustable current range of 6.00–10.00 A, the CHINT NR2-25-10 is suitable for protecting small to medium three-phase motors and provides accurate overload protection in demanding industrial environments.
Thermal overload relays such as the CHINT NR2-25-10 help prevent motor damage by detecting excessive current conditions and disconnecting the motor control circuit when overload occurs. This improves equipment reliability and helps extend motor operating life.
The NR2 series is designed for machine builders, electrical engineers and automation professionals requiring dependable motor protection with simple installation and adjustment.
