Can be mounted directly on 3RT2 contactors and 3RA23 reversing contactor assemblies; in other words, there is no need for additional wiring in the main circuit
Optimally coordinated with the technical characteristics of the 3RT2 contactors
No separate current transformer required
Variably adjustable to overshoot, undershoot or range monitoring
Freely configurable delay times and RESET response
Display of ACTUAL value and status messages
All versions with removable control current terminals
All versions with screw or spring-type 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 current unbalance, broken cables, phase failure, phase sequence, residual current and motor blocking.
Integrated counter for operating cycles counter and operating hours to support requirements-based maintenance of the monitored machine or application
Simple cyclical transmission of the current measured values, relay switching states and events to a controller
Remote parameterization
Automatic reparameterizing when devices are exchanged
Simple duplication of identical or similar parameterizations
Reduction of control current wiring
Elimination of testing costs and wiring errors
Reduction of configuration work
Integration in TIA means clear diagnostics if a fault occurs
Cost saving and space saving in control cabinet due to the elimination of AI and IO modules as well as analog signal converters and duplicated sensors
