RF828200 Lovato RF82 overload relay 60-82 amp dol 37kw

Why Choose the RF828200?

The Lovato RF828200 thermal overload relay delivers reliable motor protection across 60-82 A. This three-pole, phase failure/single-phase sensitive device features manual resetting and mounts directly on BF40 to BF94 contactors, minimising panel space and wiring. With robust construction and Lovato quality, RF828200 provides dependable overload detection for three-phase applications where continuity and equipment safety are essential.

Engineered for demanding environments, it offers IP20 frontal protection, Ui 690 V and Uimp 8 kV, with Pollution Degree 3. Rated for -20 to +55 °C operation and up to 3000 m altitude, it meets IEC/EN 60947-1 and 60947-4-1, UL508 and CSA C22.2 n° 14. Practical details include 3-pole design, 3.9 Nm terminal torque and 365 g weight.
