Fazni control relay FKV-03F

FKV-03F - Phase monitoring relay, TENSE

Product description

The FKV-03F relay is designed to protect three-phase electric motors from incorrect phase sequence, phase loss, and voltage asymmetry (set at 40%). The device includes a neutral conductor and clear LED status and error indicators.

Function and operation

• Normal operation: OUT LED lit, relay is active.

• Asymmetry error: ERR LED lit, relay is deactivated.

• Incorrect phase sequence: error indicator lit, OUT LED off, relay deactivated.

• Contacts:

  • Activated relay: 2 (COM) and 3 (NO) are switched.

  • Deactivated relay: 2 (COM) and 3 (NO) are on.
