RF92V3 Lovato RF9 overload relay BG mini contactors 1.4-2.3 amp 0.75 kw

Why Choose the 11RF92V3?

Lovato’s 11RF92V3 Thermal Overload Relay delivers dependable motor protection with phase failure/single‑phase sensitivity and manual resetting across a 1.4…2.3 A operational range. The three‑pole design integrates neatly by direct mounting on BG06, BG09 and BG12 mini‑contactors, saving space and wiring. Purpose‑built for three‑phase applications, it helps safeguard motors against overloads and loss of phase while enabling straightforward, controlled restarts via the front manual reset.

Engineered to international standards, it offers IP20 frontal protection, Ui 690 V insulation and 8 kV impulse withstand, with Ith 10 A. It operates from -20 to 55 °C and can be stored at -55 to 70 °C, up to 3000 m altitude. Conforms to IEC/EN 60947-1 and 60947-4-1, UL508 and CSA C22.2 n° 14, with Pollution Degree 3 construction.
