RS PRO 223-7792 Phase/Voltage Monitoring Relay is a high-quality protection device designed for industrial and commercial 3-phase electrical systems. It offers robust monitoring capabilities including detection of phase loss, phase sequence errors, under-voltage, over-voltage, and phase asymmetry to ensure reliable and safe operation of critical electrical equipment.
This relay is suitable for mount on DIN rails with a compact width of 17.5 mm, making it ideal for control panels with limited space. It supports both 3-wire and 4-wire 3-phase systems with a nominal operating voltage of 415 V AC and can handle contact currents up to 5 A.
The device includes configurable DIP switches allowing users to select supply voltage ranges and protection functions based on system requirements. LED indicators provide clear visual feedback on the status of voltage conditions and relay operation, facilitating quick diagnostics and maintenance.
Its adjustable ON and OFF time delays enable customization for transient conditions, minimizing nuisance tripping in fluctuating voltage environments. The relay meets various international standards such as IEC 61557-8 for electrical safety and EN 45545 for fire protection, making it reliable for applications in switchgear, control gear, machine control, and mains distribution systems.
Designed for 3-phase electrical system protection with SPDT contact. Compact DIN rail mounting with 17.5 mm width. Adjustable voltage thresholds for under and over voltage monitoring. DIP switch configuration for phase sequence and asymmetry detection.
LED fault indication for enhanced operational security. Operating temperature range from -20 °C to 60 °C. Complies with IEC 61557-8, EN 50155, IEC 61373, and EN 45545 HL-2/3 standards.
This RS PRO monitoring relay is ideal for use in industrial, automation, HVAC, manufacturing, and electrical distribution applications, ensuring longevity and protection of critical electrical assets.
