Chint Over/Under Voltage Protection Relay 80 A, 1P+N Bottom Entry (OUVR‑1/80A‑1P+N‑BE)

Rated Voltage: Operates on AC 230 V or 400 V at 50 Hz.

Rated Current: Available in settings up to 80 A, including intermediate values like 32, 40, 50, and 63 A.

Overvoltage Cut-off: Triggers at approximately 270 V ± 5 V.

Overvoltage Recovery: Resumes normal operation when voltage stabilizes between 240–260 V.

Undervoltage Cut-off: Triggers at around 170 V ± 5 V.

Undervoltage Recovery: Resumes when voltage returns to 185–195 V.

Self-Recovery Function: Automatically restores power when voltage levels return to safe ranges—ideal for unattended operations.
