NBV Voltage Unbalance Relay - Legacy
Manufacturing for NBV has been discontinued. As an alternative, please refer BA300 for battery monitor application.
The NBVIIA relay is a high speed sensitive three-phase voltage unbalance relay which is capable of detecting a small voltage unbalance in a three-phase system. The NBVIIA when applied as a protective device is normally used in conjunction with a time-delay relay. One NBVIIA relay and one timing relay are required at each terminal.
Features and Benefits
- Drawout case
Applications
- Motor bus
- Detection of upstream blown fuse
Protection and Control
- 3 phase voltage unbalance
