CHINT NR2-25-1.00 thermal overload relay with a 0.63–1.00 A adjustable current range designed for three-phase AC motor overload and phase-loss protection.
£26.19
The CHINT NR2-25-1.00 is a reliable thermal overload relay designed to provide overload and phase-loss protection for three-phase AC motors in industrial control and motor starter applications. As part of the CHINT NR2 thermal overload relay series, it is engineered for dependable motor protection and straightforward integration with CHINT contactors.
This relay uses a three-phase bimetal protection structure with adjustable current settings to help prevent motor damage caused by excessive current conditions. The NR2 series combines robust operation with practical features including temperature compensation, trip indication and flexible reset options for industrial automation systems.
With an adjustable current range of 0.63–1.00 A, the CHINT NR2-25-1.00 is suitable for protecting smaller three-phase motors and is designed for use with compatible CHINT contactor assemblies including the NC1 series.
Thermal overload relays such as the CHINT NR2-25-1.00 protect electric motors by monitoring current levels and disconnecting the motor circuit when sustained overload conditions occur. This helps reduce the risk of overheating and extends motor service life in industrial applications.
The NR2 series is designed for use in motor starters and automation systems where dependable overload protection, simple installation and compatibility with contactor assemblies are required.
