VAMP 257 Feeder and motor manager
 |
VAMP 257 feeder and motor manager is designed for double bus bar applications as the hardware can support up to 28 digital inputs and same time thirteen outputs. If the digital input need is less the output contact amount can then be greater. Supporting phase to phase, phase to ground and residual voltage connection the feeder and motor manager has all required protection stages for power distribution. The device has native Kema tested IEC 61850 communication. |
