Siemens Current monitoring relay 3UG4625-1CW30

Digital monitoring relay for residual current monitoring (with current transformer 3UL23). Adjustable range from 0.03 to 40 A, separate for warning threshold and disconnection value. Supply voltage AC/DC 24 to 240 V, 50 to 60 Hz. Start and release delay from 0.1 to 20 s. Disconnection hysteresis up to 50%, warning hysteresis fixed at 5%. Width 22.5 mm, 2 changeover contacts with or without fault memory, screw connection. Digitally adjustable residual current monitoring relay SIRIUS 3UG4 for monitoring systems for fault currents, e.g., due to dust deposits, moisture, porous cables, or capacitive fault currents. Worldwide use due to wide voltage supply and international certifications. Quick commissioning possible through menu-guided parameterization and actual value display for limit value determination. The device features a permanent display of actual value or fault type, high measurement accuracy, and continuous self-monitoring. Device replacement is possible without rewiring thanks to removable terminals. Reliable system diagnosis due to clear fault messages on the display and switchable fault memory. High flexibility and space-saving design by installing the associated transformer 3UL23 inside or outside the control cabinet. In addition to screw connection technology, the devices are also available with spring-loaded terminals for quick, maintenance-free, and vibration-resistant connections. They are optionally available with IO-Link. Note: Please order the necessary differential current transformer 3UL23 separately. Additional comprehensive accessories, such as device identification labels, insertion tabs, and cover caps, are uniform for all relays. SIRIUS relays - a program for all cases.
