Aprašymas
Digital monitoring relay for residual current monitoring (with current transformer 3UL23) Setting range 0.03...40 A separate for warning threshold and switch-off value supply voltage 24 ... 240 V AC/DC, 50 .. 60Hz ON delay and tripping delay 0.1 to 20 s Shutdown hysteresis up to 50% Warning hysteresis 5% fixed Width 22.5 mm, 2 change-over contacts with or without fault buffer screw terminal Residual current monitoring relay with digital setting SIRIUS 3UG4 for monitoring plants for residual currents, e.g. due to dust deposits or moisture, porous cables and leads, or capacitive residual currents.
Worldwide use thanks to wide voltage supply range and international certificates. Fast commissioning possible, thanks to menu-guided parameterization and actual value display for limit value determination. The devices features a permanent display of actual value and fault type, a high measuring accuracy and permanent self-monitoring. Device replacement possible without rewiring, thanks to removable terminals Reliable system diagnostics, thanks to unambiguous error messages on the display and connectable fault memory. High level of flexibility and space saving through installation of the associated 3UL23 transformer inside or outside the control cabinet.
In addition to screw terminals, all the devices are also available with spring-type terminals for fast, maintenance-free and vibration-proof connection. They are optionally available with IO-Link.
Note: Please order the necessary 3UL23 residual-current transformer separately. Additional comprehensive range of accessories, such as unit labeling plates, push-in lugs and cover caps, is standardized for all relays.
SIRIUS relays - one range for every application.
