RFE453200 Lovato RFE overload relay 6.4-32A dol 3kw-15kw star/delta at 5.5-22kw

Why Choose the RFE453200?

Engineered for dependable motor protection, the Lovato RFE453200 electronic thermal overload relay safeguards three-phase circuits against overloads and phase loss. This three-pole device is phase failure/single-phase sensitive and offers a wide 6.4…32 A operational current range. With manual or automatic resetting and direct mounting on BF09…BF38… contactors, SKU RFE453200 streamlines panel assembly while delivering precise, repeatable trip performance.

Designed for robust environments, it features IP20 frontal protection, Pollution Degree 3, and operates from -25 to 70 °C up to 3000 m altitude. Rated Ui 1000 V with 6 kV impulse withstand, it integrates securely using 3.1 to 3.1 Nm terminal torque. Compliance with IEC/EN 60947 and UL/CSA standards supports global panels, while the 195 g form factor supports compact panel layouts in control cabinets.
