SymCom 777-P2 Pump Monitor Overload Relay 200-480V 2-800FLA/Plus

SymCom’s Model 777-P2 is a fully programmable electronic overload relay. It is designed to monitor and protect any 3-phase, 200-480VAC motor drawing 2-800 full load amps (external CTs are required above 90 amps). It provides unsurpassed protection from faulty voltage, underload and overload conditions. 

The 777-P2 incorporates 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.

The 777-P2 Series units can be used as a stand-alone product, or it can be used in a network to communicate with a PC, PLC, SCADA system, or SymCom’s Solutions Software with the help of its built in RS-485 communications port. Up to 99 model 777-P2 Series units can be networked together. The 777-P2, in conjunction with SymCom’s CIO modules, supports several communication protocols including Modbus/RTU, Modbus/TCP, DeviceNet and Profibus. The units can also be connected toSymCom’s remote monitors for a simple, cost-effective way to meet new requirements for arc-flash safety.

The unit’s many features include enhanced trip classes beyond the NEMA standard trip classes. The settable trip class range is 2-60, with or without jam protection, and a secondary linear trip delay can be set with a range of 0-60 seconds. If both the trip class and linear trip delay are set, the 777-P2 will follow the faster trip time. Another feature is the automatic dry-well recovery timer that allows the unit to automatically select a restart delay based on the last cycle’s run time. This allows the 777-P2 to optimize restart delay times.

The 777-P2 can be pre-programmed with a 9-volt battery prior to actual installation. This can save a lot of time during initial installations and avoid subsequent service calls when commissioning new projects.
