Finder 6K.T1.0.000.0609 Electronic Motor Protection Relay, 690 V AC, 0.6-9 A, 1NO+1NC, DIN Rail

In industrial control panels, the Finder 6K.T1.0.000.0609 electronic motor protection relay safeguards three-phase motors from overload, phase loss, phase imbalance, and locked rotor conditions. It monitors currents from 0.6 A to 9 A and operates at voltages up to 690 V AC. The relay provides one normally open and one normally closed contact for control and signaling. It mounts on a 35 mm DIN rail and is configured via rotary potentiometers for trip class and reset mode. LED indicators show power, trip, and phase fault status.
