RFN200100 - T/O RELAY 60-100A MAN-AUTO

Why Choose the RFN200100?

Lovato RFN200100 is a thermal overload relay for robust three-phase motor protection. It is three-pole and non phase failure / non single-phase sensitive, with a wide 60...100 A operational current range. Choose manual or automatic resetting to suit your control scheme, and benefit from screw mounting, IP20 frontal protection, 1000 V rated insulation and 6 kV impulse withstand capability.

Designed for Lovato B series contactors, this relay delivers reliable performance across -25 to 60 °C operating temperatures and up to 3000 m altitude. It conforms to IEC/EN 60947-1 and 60947-4-1, as well as UL508 and CSA C22.2 n° 14, supporting global panel compliance. A sturdy 3-pole build and clear IP20 front make integration straightforward.
