Three-phase monitoring/protection relay monitors phase/asymmetry/voltage failure

Description

Three-phase monitoring/protection relay for sequence control, tripping, phase asymmetry, overvoltage, undervoltage, neutral wire tripping with timer. Protective monitoring relay FKM-05/05F (TENSE)

Phase protection relays are designed to protect three-phase loads from damage caused by line voltage.

• Overvoltage: 300 V (fixed)
• Undervoltage: 140V (fixed)
• Asymmetry: 5% – 25% (adjustable)

• Timer: 0.1 s – 20 s (adjustable)

• Phase failure protection

• Neutral phase failure protection

• Phase sequence control (FKM-05F)

• DIN rail mounting

• Width 35.6 mm
