Digital monitoring relay for residual current monitoring with residual current transformer 3UL23 for IO-Link Setting range 0.03 A to 40 A separate for warning threshold and switch-off value Start-up and tripping delay 0 to 999.9 s Switch-off hysteresis up to 50% Warning hysteresis 5% fixed Width 22.5mm, 2 changeover contacts with or without fault memory Screw connection Digitally adjustable residual current monitoring relay SIRIUS 3UG4 for monitoring systems for residual currents, e.g. due to dust deposits, moisture, porous cables or capacitive residual currents. Worldwide use thanks to wide voltage supply and internationally validated. Fast commissioning possible thanks to menu-guided parameterization and actual value display for limit value determination. The device has a permanent display of the actual value or type of error, high measurement accuracy and permanent self-monitoring. Device can be changed without rewiring thanks to removable terminals. Reliable system diagnostics thanks to clear error messages on the display and switchable error memory. High flexibility and space savings through installation of the associated 3UL23 converter inside or outside the control cabinet.In addition to screw connection technology, the devices are also available with spring-loaded connections for quick, maintenance-free and vibration-proof connections. They are optionally available with IO-Link.Note: Please order the necessary 3UL23 residual current transformer separately. Other comprehensive accessories, such as device identification plates, push-in tabs and cover caps, are standard for all relays.SIRIUS relays - a program for all occasions.
