Siemens 3RR22422FW30 3RR2242-2FW30 Monitoring relay can be mounted on contactor 3RT2, size S00 content_copy

Monitoring relay, can be attached to 3RT2 contactor, size S0 standard, digitally adjustable Apparent/active current monitoring 4...40 A, 20...400 Hz, 3-phase supply 24-240 V AC/DC 1 changeover contact, 1 semiconductor output for alarm and warning Monitoring for current overshoot and undershoot Phase failure, wire break Phase sequence Residual current Blocking current Warning and alarm thresholds with or without error memory Start-up delay 0-99 s Noise peak suppression 0-30 s Pause after error 0-300 min Spring-loaded technology SIRIUS 3RR2 monitoring relay for connecting to SIRIUS 3RT2 contactors or for stand-alone installation for multi-phase current monitoring of the entire system or the driven process. Reliable monitoring for cable breakage, phase failure, phase sequence, residual current, motor blocking and much more creates increased system availability. Actual value displays, status messages and clear error messages enable fast and reliable diagnosis. Control connection via IO-Link is also possible.You also save costs because only one device is required to monitor a motor along the entire torque curve and no separate current transformers are needed. Direct attachment to the 3RT2 contactors means there is no additional wiring work in the main circuit. You also benefit from the wide-voltage power supplies for worldwide use.Analog adjustable, 2-phase versions and digital adjustable, 3-phase versions (with and without IO-Link) are available, each in three sizes with different current measuring ranges, with two different supply voltages and two connection types.Suitable carriers are available for individual installation of the 3RR2 monitoring relays.SIRIUS relays - a program for all cases.
