The 777-KW/HP-P2 is a 3-phase current and voltage monitor that provides unsurpassed protection by combining overload, voltage, phase loss and reversal, voltage and current unbalance, power monitoring*, and underload trip based on power into one efficient unit. 只要电流与负载特性呈非线性或变化很小，就需要欠功率跳闸功能。 一般来说，较小的电机和低速电机在正常负载范围内电流变化很小。 轻载运行的较大电机也会在工作负载范围内显示出较小的电流变化。 The low and high power protection feature increases reliability for non-linear motors where the load characteristic has little change.

For standalone applications, these units incorporate a 3-digit LED display that is used for programming, providing real-time operational information, and displaying diagnostic codes to aid in troubleshooting a fault condition. These units also feature a communications network port that can be used with communication modules, listed in the 777 accessories section, to form a Modbus, DeviceNet**, Profibus, or Ethernet network. 最多可从PC、PLC或SCADA系统远程监控99台装置，并通过带有可选解决方案软件的PC进行数据记录。

*Low current trip and high power trip are network programmable only. **DeviceNet is a trademark of its respective owner.
