Overload Relays
SymCom’s Model 777-HVR-P2 is a fully programmable electronic overload
relay. It is designed to monitor and protect any 3-phase, 340-480VAC motor
drawing 2-800 full load amps (external CTs are required above 90 amps).
This unit’s 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 777-HVR-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.
Model 777-HVR-P2
Features:
• Protects 3-phase motors from:
• High voltage

• Network programmable
• Programmable with 9-volt battery prior to
installation
• Automatic reset with three separate restart delay
timers, or manual reset
• Tamper guard
• RS-485 communications port (communications
module sold separately)
• 3-digit LED diagnostic display
• Last fault memory
• UL and ULC listed
• CE compliant
• CSA approved
• Surface or DIN rail mount
• 5-year warranty
• Made in USA
The 777-HVR-P2 Series can be used as stand-alone products or
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. The 777-HVR-P2, in conjunction with
SymCom’s CIO modules, supports several communication protocols
including Modbus/RTU, Modbus/TCP, DeviceNet and Probus. The
units can also be connected to SymCom’s remote monitors for a simple,
cost-effectivewaytomeetnewrequirementsforarc-ashsafety.
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-HVR-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-P2 to optimize
restart delay times.
The 777-HVR-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.
Common applications include conveyor systems, HVAC equipment, saws
and grinders, fan motors and almost any pumping application, to save the
SS-777-HVR-P2_C
cost and extra wiring associated with a CPT.
