The 777-575-KW/HP-P2 is a 3-phase current and voltage monitor designed for motor and pump protection, operating with input voltage from 500 to 600 VAC and supporting motor full load currents from 2 to 800 A using external current transformers above 90 A. It features a built-in 3-digit LED display, programmable settings for voltage and current, three selectable restart options, and remote reset capability. The unit provides SPDT relay contacts rated at 480 VA at 240 VAC, supports DIN rail or surface mounting, and measures 77.47 mm high, 97.79 mm wide, and 128.27 mm deep. It complies with UL508, UL1053, IEC 60947-1, IEC 60947-5-1, and CSA C22.2 standards, and is rated for operation from -20°C to 70°C with IP20 protection. The device includes overload, phase loss, voltage and current unbalance, and underpower trip protection, with accuracy of ±1% for voltage and ±3% for current under 100 A direct.
The 777-575-KW/HP-P2 three-phase current and voltage monitor provides protection with input voltage from 500–600 V ac and motor full load ampere range as follows: 2–20 A (looped conductors required); 20–90 A direct; 90–800 A (external CTs required).
