Request a quote and... Price & Availability It is part of the NRT series, which is known for its reliability and compact design. The relay is suitable for use with contactors up to 32A and features a manually adjustable current setting range from 23A to 32A. It is a 3-pole device with a Class 10A trip characteristic, meaning it will trip within 10 seconds at 7.2x the current setting, providing fast and reliable protection. This relay is equipped with a differential mechanism for phase-loss protection, ensuring that the motor is disconnected in the event of a single-phase failure. It also includes a trip-free mechanism, which guarantees that the relay will trip even if the reset button is held in the closed position. The NRT2832 has both manual and automatic reset modes, selectable via a switch, and features a test button for functional verification. The device is designed for DIN rail or screw mounting, making it versatile for various panel configurations. The NRT2832 is CE and CCC certified, meeting international standards for safety and performance. It is commonly used in industrial automation, HVAC systems, pumps, fans, and other motor-driven equipment. With its robust construction and high electrical endurance, the NRT2832 ensures long service life and minimal maintenance. It is an ideal choice for OEMs and panel builders seeking a cost-effective yet reliable motor protection solution. The CHINT NRT2832 is a thermal overload relay designed for protecting AC motors against overload, phase loss, and prolonged starting times. Basic Product Information 3-pole protection with differential phase-loss detection Class 10A trip characteristic for fast response Manual and automatic reset modes selectable Trip-free mechanism ensures reliable tripping Test button for functional check DIN rail or screw mounting options CE and CCC certifications Adjustable current setting range 23-32A Technical Specifications Version & Model Difference The NRT2832 is part of the NRT28 series, which includes models with different current ranges such as NRT2801 (0.1-0.16A), NRT2802 (0.16-0.25A), up to NRT2832 (23-32A). The series shares the same physical dimensions and features, but the current setting ranges differ. The NRT28 series is an updated version of the older NR2 series, offering improved accuracy and a more compact design. The NRT2832 specifically replaces the NR2-25G (23-32A) model. Application Scenarios Does the NRT2832 provide phase-loss protection? Yes, the NRT2832 is equipped with a differential mechanism that detects phase loss and trips the relay to protect the motor from running on two phases. Can the NRT2832 be used with contactors from other brands? While it is designed to mount directly on CHINT NTC28 contactors, it can be used with other contactors of similar rating (up to 32A) if a suitable mounting adapter is used. Always ensure proper mechanical and electrical compatibility. What is the trip class of the NRT2832? The NRT2832 has a Class 10A trip characteristic, meaning it will trip within 10 seconds at 7.2 times the current setting, providing fast protection against overloads. What is the current setting range of the CHINT NRT2832? The NRT2832 has an adjustable current setting range from 23A to 32A, allowing it to protect motors with full-load currents within that range.
