Monitoring/protection three-phase relay for control of overvoltage, undervoltage, asymmetry sequence

Description

Three-phase monitoring/protection relay for controlling sequence, trip, phase asymmetry, overvoltage, undervoltage, neutral trip with timer and display. Protective monitoring relay FKV-03HF (TENSE)

The phase protection relays are designed to protect the three-phase loads from damage caused by mains voltage.

• Voltage: 400V – 480V AC (adjustable)
• Undervoltage: 260V – 360V AC (adjustable)
• Asymmetry: 5% – 25% (adjustable)
• Phase sequence control
• Timer: 1 sec. – 30 sec.(adjustable)

• DIN rail mounting

• Width 23.15 mm
