YOSHINE Single-Phase Automatic Reset Voltage Protection Relay
The YX742SLR2 single-phase automatic reset voltage protection relay is designed for medium to high voltage applications, supporting a working voltage range of 100-265VAC/DC. Featuring a double-pole double-throw (DPDT) output, this relay quickly disconnects the load when voltage exceeds or drops below the set range, protecting motors, transformers, and other sensitive equipment from potential damage. With a hysteresis voltage of 5%, it avoids frequent operations caused by minor voltage fluctuations, ensuring stable system performance.
Equipped with an automatic reset function, the relay restores operation when voltage returns to a safe range, eliminating the need for manual intervention and simplifying maintenance processes. The recovery delay is ≤30 seconds, providing sufficient buffer time to ensure equipment safety during transient voltage variations. Its compact design and easy installation make the YX742SLR2 suitable for industrial automation, power systems, and building electrical control applications.
This relay combines reliability with precise performance, helping businesses reduce equipment failure rates, extend operational lifespan, and enhance overall electrical safety management. Its straightforward setup and consistent operation make it a practical choice for facilities seeking dependable voltage protection.
