The Littelfuse SymCom 777-ACCUPOWER is a 3-phase electronic motor overload relay for 190-480 V AC motors drawing 2-800 full-load amps (2-25 A (looped conductors), 25-90 A direct, 80-800 A with external CTs). It provides overload protection and calculates motor output (shaft) power. Power: Calculates motor output (shaft) power from the entered hp, full-load amps, efficiency and power factor; optional COM 4-20 analog output proportional to shaft power.
Overcurrent trip class: 5, 10, 15, 20 or 30 (J prefix enables jam protection). Restart delays: 3 programmable timers: rapid cycle, motor cool-down and dry-well recovery. Reset: Automatic, semi-automatic or manual (selectable); push button on the relay or remote with a 777-MRSW or OL-Reset kit. Display: 3-digit LED display: programming, real-time voltage and current, last fault code. Networking: Limited Modbus with the RS485MS-2W module; COM 4-20 analog output module; RM1000 / RM2000 remote monitors.
Output: 1C SPDT, 10 A at 240 V AC. Mounting: DIN Rail/Panel Mount. Dimensions: 77.47 x 97.79 x 128.27 mm (3.05 x 3.85 x 5.05 in), H x W x D.
It operates from -40 to +70 °C and can be stored from -40 to +80 °C. Approvals: UL 508, UL 1053, CSA C22.2, CE.
