The Littelfuse SymCom 777-KW/HP-P2 is a 3-phase electronic motor overload relay for 200-480 V AC motors drawing 2-800 full-load amps (external CTs required above 90 A). It protects against overload, underload (power), phase loss, phase reversal, voltage and current unbalance, undervoltage, overvoltage, low and high power (network programmable). Power: Real-time kW and hp on the display; underload trip based on power; low and high power trip (network programmable).
Overcurrent trip class: 02-60, J02-J60, L00-L60 or Off (J enables jam protection, L linear trip). 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, current, kilowatts and horsepower, last fault code. Networking: Modbus, DeviceNet, Profibus or Ethernet via optional communication module; up to 99 units networked.
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 -20 to +70 °C and can be stored from -40 to +80 °C. Approvals: UL 508, UL 1053, CSA C22.2, CE.
