Overview
The SIRIUS 3RR2 current monitoring relays are suitable for the load monitoring of motors or other loads. The 3RR2 current monitoring relays can be integrated directly in the starter by mounting onto the 3RT2 contactor; separate wiring of the main circuit is not required. Separate transformers are also not required. For a line-oriented configuration or simultaneous use of an overload relay, terminal brackets for stand-alone installation are available for separate standard rail mounting.
Directly Mountable onto 3RT2 Contactors, i.e. No Additional Wiring Outlay in the Main Circuit
Optimally Coordinated with the Technical Characteristics of the 3RT2 Contactors
Variably Adjustable to Overvoltage, UnderVoltage or Range Monitoring
Freely Configurable Delay Times and RESET Response
Display of ACTUAL Value and Status Messages
All Versions with Removable Control Current Terminals
Simple Determination of the Threshold Values Through Direct Reference to Actually Measured Values for Setpoint Loading
Range Monitoring and Selectable Active Current Measurement Mean That Only One Device for Monitoring a Motor Is Required Along the Entire Torque Curve
In Addition to Current Monitoring It is Also Possible to Monitor for Broken Cables, Phase Failure, Phase Sequence, Residual Current and Motor Blocking
Digitally adjustable, LCD, open-circuit or closed-circuit principle, 1 CO, semiconductor output, 3-phase current monitoring, active or apparent current monitoring, phase sequence monitoring, residual current monitoring, blocking current monitoring, reclosing delay time 0-30 min., startup delay 0-90 sec., separate setting for warning and alarm thresholds.
