777-HVR-LR-P2 MotorSaver

777-HVR-LR-P2 MotorSaver - In Stock
Is a fully programmable electronic overload relay. It is designed to monitor and protect any 3-phase 340-480VAC motor drawing 1-9 full load amps (external CTs are required above 9 amps).

777-HVR-LR-P2 replaces 777-HVR-LR and 777-HVR-LR-P/P1

777-HVR-LR-P2 MotorSaver Form C contacts are pilot duty rated at 470VA @ 600VAC for applications where a control power transformer (CPT) is not used on a 480V system. The unit provides unsurpassed protection from faulty voltage, underload and overload conditions. Common applications include conveyor systems, HVAC equipment, saws and grinders, fan motors and almost any pumping application, to save the cost and extra wiring associated with a CPT. The -LR (low range) models allow for easier installation in low amperage applications. This unit can be used as a stand-alone product or the RS-485 communications port can be used to form a network to communicate with a PC, PLC or SCADA system. The 777-HVR-LR-P2 units can be used with CIO modules produced by SymCom for several types of communication protocols. Up to 99 model 777-HVR-LR-P2 units can be networked together and monitored and controlled by SymCom’s Solutions software. The units can also be connected to SymCom’s remote monitors for a simple, cost-effective way to meet new requirements for arc-flash safety.
The 777-HVR-LR-P2 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.
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 trip class and linear trip delay are set, the 777-HVR-LR-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-HVR-LR-P2 to optimize restart delay times.

The units 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.
