Three-phase voltage relay VP-3F40A
- Three-phase voltage relay VP-3F40A
VP-3F40A three-phase voltage relay
Three-phase voltage relay VP-3F40A is designed to protect single-phase or three-phase consumers from voltage fluctuations, phase imbalance, phase loss, phase sequence control. The device prevents failures and extends the life of electrical equipment. With selectable operation as three-phase or three independent single-phase relays.
Programmable settings:
- Value of upper and lower voltage trip limits
- Delay time for switching on the load
- Value of allowable phase asymmetry
- Synchronous / asynchronous mode of operation
- Control of alternating phase sequence
All set values are stored in non-volatile memory.
Manufactured in Ukraine.
