Product details
Monitoring Relay - 3RR range
SIRIUS 3RR21 and 3RR22 current monitoring relays are suitable for the load monitoring of motors or other loads.
In 2 or 3 phases they monitor the rms value of AC currents for overshooting or undershooting of set threshold values
Monitoring relay attachable to contactor 3RT2
For contactor size S00 or S0
Analogue or digital adjustable
For alarm and warning monitoring for current overshoot/undershoot phase failure, wire break phase sequence fault current blocking current warning and alarm
Screw connection/Spring Clamp
