RFN380250 - T/O RELAY 1 6-2 5A MAN/AUTO

Why Choose the RFN380250?

Lovato RFN380250 thermal overload relay safeguards three‑phase motors within the 1.6…2.5 A operating range. It mounts directly on BF09…BF38 contactors and supports manual or automatic resetting in a three‑pole design. This type is non phase failure / non single‑phase sensitive, offering reliable motor protection for BF series control gear in demanding industrial environments.

Built for compliance and longevity, the relay provides Ui 690 V and 6 kV impulse withstand, with IP20 frontal protection and pollution degree 3. Rated Ith 10 A, it operates from −25 to 60 °C and up to 3000 m altitude. Terminal tightening torque is 2 to 2.5 Nm. Conforms to IEC/EN 60947‑1 and 60947‑4‑1, UL508 and CSA C22.2 n° 14.
