Phase control relay FKV-03F

Phase monitoring relay for protection of a three-phase electric motor - monitoring of phase sequence, presence and asymmetry (fixed setting 40%), with neutral conductor, Tense

Phase monitoring relay for protection of a three-phase electric motor - monitoring of phase sequence, presence and asymmetry (fixed setting 40%), model FKV-03F, manufacturer TENSE.

Device operation and use

Normal operation (no faults): When the phases are within the correct values and sequence, the relay is energized and the OUT LED is lit.

Asymmetry fault: If any phase is outside the normal range, the ERR LED goes off and the relay is deactivated.

Incorrect phase sequence (Phase Sequence Error): The phase sequence error indicator remains lit, the OUT LED goes off, and the relay is deactivated.

Relay energized: Contacts 2 (COM) and 3 (NO) are energized. Relay deactivated: Contacts 2 (COM) and 3 (NO) are closed.
