Features
The Chint NXR-38 provides stable and reliable performance with several integrated features:
Overload and Phase Failure Protection: Uses a bimetallic element to detect excessive current and phase loss, which can cause motor damage. Temperature Compensation: The relay has a compensation mechanism to maintain consistent trip accuracy regardless of ambient temperature changes.
Manual and Automatic Reset: Users can choose between manual or automatic reset modes after the relay trips due to a fault condition.
Test and Stop Function: Includes a test button to verify the functionality of the trip mechanism and a stop button for manual intervention.
Release Indicator: A visual indicator (usually a red flag or LED) signals when the relay trips.
Compatibility: Designed to be compatible with the Chint NC1-32 series contactors, allowing seamless integration into motor control circuits.
