Current Monitoring Relays

Current Monitoring Relays

SIRIUS 3UG4 and 3RR2 monitoring relays facilitate the monitoring of various electrical and mechanical parameters in the feeder and reliable system protection against damage. The relays can be mounted in stand-alone assembly (3UG4); alternatively, the 3RR2 current monitoring relay can be directly integrated in the feeder by easy plug-on mounting on SIRIUS 3RT2 contactors.

SIRIUS monitoring relays not only feature freely parameterizable threshold values and manifold adjustment options, but also provide conclusive diagnostics and are even able to correct an incorrect phase sequence autonomously. Numerous versions are also available with IO-Link interface for connection to the control. Find out more about IO-Link:
