Digital monitoring relay for current, active current, voltage, power factor, and power monitoring up to 690V AC/DC and 15A. Supply voltage AC/DC 24 to 240V, 50 to 60Hz. Start and release delay from 0.1 to 999.9 seconds. Equipped with 2 changeover contacts and spring terminal connection. The digitally adjustable monitoring relay SIRIUS 3UG5 monitors the power factor and active current for exceedance, for example, in contaminated filter systems, or for undercutting, such as in cases of belt breakage or pump dry running. It is suitable for worldwide use due to wide voltage range and international certifications. The relay also monitors smaller single-phase motors with a no-load current below 0.5 A. Implicit monitoring for cable break and phase failure is possible. The measurement principle of power factor or active current is selectable. The space requirement in the control cabinet is low due to the narrow design. Reliable diagnostics through display of actual value and status messages. All versions feature detachable terminal blocks. In addition to screw connection technology, the devices are also available with spring terminal connection for quick, maintenance-free, and vibration-resistant connections. They are optionally available with IO-Link. Additionally, devices with SIL 1/PL c certification are available. The comprehensive accessories, such as device identification labels, replacement terminals, and sealing covers, are uniform for all relays. The monitoring relays 3UG5 replace the proven series 3UG4. SIRIUS relays - a program for all cases.
