Three-element thermal overload relay designed for the most demanding installations and to be paired with compatible SC-NEXT Frame 65X contactors for a fully integrated, high-capacity motor starter assembly. The integrated open-phase detector (3E function) guards against the three most common causes of motor failure: overload, locked-rotor current, and single-phasing. Where a standard two-element relay would miss a phase-loss fault entirely, this relay won’t. Three-element sensing ensures balanced monitoring across all phases at the upper end of the current range, where the consequences of undetected faults are greatest, and manual reset keeps post-trip control firmly in the operator’s hands. The relay is available across a wide range of current settings to match your specific motor load and pairs with any SC-NEXT Frame 65X contactor to deliver a fully certified motor starter solution compliant with IEC 60947-4-1 and JIS C 8201-4-1.
