Chint NXR Thermal Overload Relay (30–40 A)

Motor Protection
Ideal for AC motors (50 Hz/60 Hz) operating up to 690 V, with adjustable current settings tailored to motor specifications.

Wide Adjustment Range
Adjustable range typically from 0.1 A up to 630 A, depending on the specific NXR variant. The 30–40 A range aligns with the NXR‑100 model designation.

Thermal and Phase Fault Guarding
Internally uses bi-metal thermal detection with phase-loss protection, safeguarding motors against single-phasing conditions. Supports both plug-in (with contactors) and independent mounting.

User Controls & Indicators
Includes features such as:

• Manual and/or automatic reset (model-dependent)

• Trip indication

• Test and stop functions

• Temperature compensation for consistent performance

• One normally open (NO) and one normally closed (NC) auxiliary contact for signaling or interlocks

Standards Compliancy
Built to IEC/EN 60947-4-1 and IEC/EN 60947-5-1 standards, ensuring safety and reliability in industrial use.
