Protective three-phase monitoring relay for phase failure/asymmetry/trace monitoring

Phase control relay with phase fault, phase loss, asymmetrical phases (fixed 30%) control, single-rail installation FKV-11, TENSE

Phase control relay operating algorithm: if all three phases or line voltage are connected in the correct sequence, all phase voltages are within permissible limits - the relay is in operating condition and contacts 2-3 are closed, LED OUT is on. If the voltage of any phase changes by more than 30% (or if the multidirectional total change exceeds this limit), the ASM LED lights up and contacts 2-3 open, contacts 1-2 open and the OUT LED turns off. When the voltage difference returns to the specified range, the contacts switch back.
