    Overload Relays Monitoring, control, and protection are critical and necessary functions in motor and pumping applications. SymCom’s single-phase and three-phase UL listed enhanced overload relays monitor for both line-side voltage problems and load-side current faults, providing an added layer of protection over voltage monitors and other basic overload relays. All SymCom overload relays are user configurable and cover a wide range of voltages and currents, making them the most versatile in the industry. A standard feature of the entire family of SymCom overload relays is a communications port which provides easy connectivity to a SCADA system, PLC, or virtually any network through the use of a communications module. The communications port allows remote monitoring of motor operations and fault conditions through easy connectivity to SymCom’s Remote Monitors, aiding compliance with arc flash safety regulations.

    Overload Relay

    Available Models:  

    The Model 777 / 77C 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). The 77C (family of products) is for single-phase 100-240VAC applications and the 777 (family of products) is for 3-phase 200-480VAC

    applications, with several specialized units for other voltage ranges and unique applications. Common applications include conveyer 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, 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 last or active 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
