The 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 A). The 777-HVR-SP and 77C (family of products) are for 1-phase 100 to 240 VAC applications. Common applications include conveyor systems, HVAC equipment, saws and grinders, fan motors and almost any pumping application. All of the overload relays provide unsurpassed protection by combining overload, underload and voltage 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 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.
