Symcom Motor Saver - 3-Phase Overload Relay/500-600V/2-800FLA/Plus

777-575-P2
is a fully programmable electronic overload relay designed to protect any motor drawing 2-800 full load amps (external CTs are required above 90 amps).  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, underload, voltage and power monitoring functions in one package. The overload relays have a 3-digit display for viewing real-time voltage and current and for displaying the fault code (to simplify diagnostics) when tripped for a fault condition. The units can be used as a stand-alone product or the communications port can be used to form a Modbus, DeviceNet, Profibus, or Ethernet network to monitor up to 99 units from a PC, PLC, or SCADA system, and for data logging through a PC with SymCom’s Solutions software. The communications port can also be used for remote monitoring to improve safety for personnel by allowing them to monitor and control motor operation without opening the electrical cabinet. This capability allows for a simple, cost-effective way to meet new requirements for arc-flash safety.
