777-HVR-P2规格书详情
Description
The 777 unit is a fully-programmable, electronic overload relay designed to protect any motor drawing 2-800 full load A
(external CTs are required above 90 A). The 777 (family of products) is used for 3-phase, 200-480 V ac applications, with
several specialized units for other voltage ranges and unique applications. Common applications include conveyor systems,
HVAC equipment, saws and grinders, fan motors, and almost any pumping application. Some unique applications include
use with a Subtrol* equipped Franklin submersible motor to detect high motor temperatures and applications where a fast
linear trip is required.
All of the overload relays provide unsurpassed protection by combining overload, voltage, phase loss and reversal,
voltage and current unbalance, power monitoring, and underload based on current — all in one package. For standalone
applications, the 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 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. Up to 99 units can be remotely monitored and controlled from a PC,
PLC, or SCADA system, and data logging through a PC with the optional Solutions software. This capability allows for a
simple, cost-effective way to meet new requirements for arc-flash safety.
Applications
• Conveyor systems
• HVAC equipment
• Saws and grinders
• Fan motors
FEATURES BENEFITS
Built-in display Visual indication for programming, viewing real-time voltage or
current, and last fault code
Programmable voltage and current settings Allows usage on wide range of systems
3 selectable restart options Choose from automatic, semi-automatic, or manual to best meet
individual application needs
3 programmable restart delay timers Program separate restart delay time for rapid cycle protection, motor
cool down, and dry-well recovery
Remote display compatibility
Increases safety through remote display of real-time data and fault
history without the need to open the cabinet. Aids with arc flash
safety regulations
Flexible reset Reset can be done through a push button on the relay or remotely with
optional 777-MRSW or OL-Reset remote reset kit
