Littelfuse 777-575-HRG-P2 is a versatile and reliable protection relay. It has a pilot duty output load rating of 480 VA at 240 Volts B300 and a general-purpose output load rating of 10 A at 240 Volts. With a termination torque of 7 in-lbs, it ensures secure connections. It operates in a wide AC line frequency range of 50/60 Hz and is suitable for humid environments. The voltage and current accuracy is excellent, with ±0.5% and ±1% deviation, respectively. It offers surge protection according to IEC 61000-4-5 Level 3 and Level 4 standards. The restart delay range can be adjusted according to the fault type. It provides a voltage unbalance trip point of 2-25%, overvoltage trip voltage of 451-660 V, and undercurrent trip point of 0-98 A. It also has a wide CT ratio range of 1-10. The timing accuracy is ±0.5 s, and the current accuracy is ±3%. It has a rapid cycle timer with a range of 0-999 s and multiple overcurrent trip classes. The address can be set via COM (C00-C07) or RS-485 (A01-A99). It offers ±1% voltage accuracy, ±15% ground fault accuracy, and a full load amp range of 2-20A (looped conductors required) and 20-90A (direct). It complies with IP20 protection class (finger safe) and has a pollution degree of 3. It has a short circuit rating of 100 kA and an undercurrent trip delay range of 2-999 s. The current unbalance trip point can be set between 2-50% or disabled, and the ground fault current trip point can be adjusted between 1-10A. The ground fault trip delay is 0s by default.
