Phase monitoring relay for three-phase electric motor protection - monitoring phase sequence, presence, and asymmetry (fixed setting at 40%), with neutral conductor, Tense
Phase monitoring relay for three-phase electric motor protection - monitoring phase sequence, presence, and asymmetry (fixed setting at 40%), model FKV-03F, manufacturer TENSE.
Device operation and usage
Normal operation (no error): if the phases are within the correct value and sequence, the relay is energized and the OUT LED is on.
Asymmetry error: if a phase is out of the normal range, the ERR LED turns off and the relay deactivates.
Incorrect phase sequence (phase sequence error): the phase sequence error indicator is steadily lit, the OUT LED turns off, and the relay deactivates.
Relay energized: contacts 2 (COM) and 3 (NO) are energized. Relay de-energized: contacts 2 (COM) and 3 (NO) are closed. Technical specifications Operating voltage (Un): 3 x 380 V AC with neutral conductor Frequency: 50/60 Hz Power consumption: <6 VA Operating temperature: from -20 °C to +55 °C Allowed asymmetry: ~40% Contact: 5 A, 250 V AC for resistive load Display: 3 LEDs Mounting: DIN rail Weight: <150 g |
