The Lovato RFA826500 is a three-pole thermal overload motor protection relay designed to protect three-phase motors against overload and phase failure conditions. Part of the Lovato RFA82 motor protection relay range, it provides an adjustable operational current range of 46–65 A and is designed for direct mounting on Lovato BF40–BF94 contactors.
The RFA826500 is phase-failure and single-phase sensitive and features automatic resetting for applications requiring the relay to reset automatically after a trip. Its Class 10A tripping characteristic, integrated test button and trip indicator provide practical motor protection, commissioning and fault indication functionality.
With a rated operational and insulation voltage of 690 V, an 8 kV rated impulse withstand voltage and an operational frequency range of 0–400 Hz, the RFA826500 is engineered for industrial motor starter applications. Its direct mounting arrangement enables compact integration with compatible BF contactors inside electrical control panels and machinery.
Thermal overload relays help protect electric motors by responding when sustained current exceeds the selected operating range. The Lovato RFA826500 combines an adjustable 46–65 A current setting with phase-failure sensitivity and Class 10A tripping performance for dependable protection of compatible three-phase motor circuits.
Designed for direct mounting on Lovato BF40–BF94 contactors, the RFA826500 supports compact motor starter construction. Its automatic reset function, test button, trip indicator and auxiliary contacts provide practical functionality for industrial motor control and automation systems.
