Voltage Monitoring Relays

The KRIWAN INT69 UY Diagnose voltage monitoring relay series offers advanced, real-time diagnostics and protection for sensitive electrical components, drives, and industrial consumers. Designed to safeguard systems from common issues such as phase sequence errors and voltage imbalances, the INT69 UY Diagnose relays ensure reliable operation and help prevent costly failures. These devices continuously monitor electrical parameters and temperature levels to detect faults at an early stage, thereby supporting predictive maintenance and enhancing overall system safety.

Available in the distinct ‘All-in-One’ variant, these relays are suitable for a wide range of applications. It features configurable settings, push-in terminals for quick wiring, options for both PTC and Pt1000 temperature monitoring, including neutral conductor break detection and phase monitoring including phase sequence, phase failure, phase asymmetry, over voltage and under voltage monitoring.

The INT69 UY Diagnose series is engineered for seamless integration into supervisory control systems, enabling remote monitoring and system integration via standardized communication interfaces. With integrated LED status indicators and a dedicated diagnostic interface, these relays provide clear and immediate feedback on system conditions, ensuring that any deviations from normal operating parameters are promptly addressed. Its robust design not only guarantees high performance but also simplifies installation and routine maintenance, significantly reducing downtime. Certified for global use, they are ideally suited for applications in chillers, refrigeration units, wastewater systems, and building or factory automation, delivering a robust and user-friendly solution for modern electrical system protection.
