RFA828200 - OVERLOAD RELAY 60-82A BF40-BF80 AUTO

Why Choose the RFA828200?

Designed for dependable motor protection, the Lovato RFA828200 thermal overload relay safeguards three-phase installations with phase failure/single-phase sensitivity. Covering 60–82 A applications and featuring automatic resetting, it helps restore service quickly after transient overloads. The three-pole design mounts directly on BF40 to BF94 contactors, simplifying panel layouts and reducing wiring. With IP20 frontal protection and robust insulation ratings, it integrates cleanly into industrial control assemblies.

Built to recognised standards including IEC/EN 60947-1 and 60947-4-1, plus UL508 and CSA C22.2 n° 14, this relay offers 690 V rated insulation and 8 kV impulse withstand for demanding environments. Operating from -20 to 55 °C up to 3000 m, it performs reliably in control panels. A compact 3-pole unit with IP20 frontal degree, it is supported by a Sustainability certification.
