CHINT NR2-630 Plug-In Thermal Overload Relay 3-Pole

CHINT NR2-630 is a plug-in, 3-pole thermal overload relay designed to protect 3‑phase motors in industrial motor starters. It targets the 200–315 A current setting range and is rated for up to 600 V, making it suitable for common motor circuits in harsh industrial environments. As part of the NR2 family, it shares a broad overall current capability (0.1–630 A across NR2 devices) while the NR2-630 variant is specifically configured for the 200–315 A band, enabling precise overload protection for mid‑size motors. The relay complies with IEC/EN 60947-2 and 60947-4-1 standards, and its ambient operating range is -5 to +40 °C, which supports reliable operation in typical workshop and factory settings. Designed for plug-in mounting with CHINT contactors, NR2-630 provides straightforward replacement and integration within three‑phase control circuits.
