Looking for prices?

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 VAC 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.
  • 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
