Current Monitoring Relays

Directly mountable onto 3RT2 contactors and 3RA23 reversing contactor assemblies, i. e. no additional wiring outlay in the main circuit
Optimally coordinated with the technical characteristics of the 3RT2 contactors
No separate current transformer required
Versions with wide voltage supply range
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 terminals 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 broken cables, phase failure, phase sequence, residual current and motor blocking.
