CHINT NR2-36-32 thermal overload relay with adjustable 25 A to 32 A current range for overload and phase failure protection of three-phase AC motors.
£34.93
The CHINT NR2-36-32 is a high-performance thermal overload relay designed to protect three-phase AC motors against overload, phase failure and excessive current conditions in industrial motor control systems. As part of the robust CHINT NR2 thermal overload relay series, this relay delivers dependable motor protection for automation systems, machinery and OEM electrical panels.
Built with a precision three-phase bimetal tripping mechanism, the NR2-36-32 continuously monitors motor current and disconnects the circuit when abnormal operating conditions occur. Integrated temperature compensation and phase loss sensitivity improve protection accuracy while helping reduce motor damage and costly downtime.
With an adjustable current range of 25 A to 32 A, the NR2-36-32 is suitable for larger industrial motors used in conveyors, compressors, pumps, fans and processing equipment. The relay is engineered for direct mounting onto compatible CHINT NC1, NC2 and NC7 contactors, enabling compact and efficient motor starter assemblies.
Thermal overload relays are essential for protecting electric motors against overheating caused by excessive current draw, mechanical overload or phase imbalance. The CHINT NR2-36-32 continuously monitors motor current and trips the associated contactor when unsafe operating conditions are detected.
The NR2 series is widely used in industrial automation systems, OEM machinery and motor control centres where dependable motor protection and compact installation are essential. Its direct mounting configuration simplifies panel assembly and maintenance operations.
