Why Choose the Lovato RFN200100 Motor Protection Relay?

The Lovato RFN200100 is a three-pole thermal overload motor protection relay designed for three-phase motor circuits requiring adjustable overload protection. Part of the Lovato RFN200 motor protection relay range, it provides an adjustable operational current range of 60–100 A and is intended for use with Lovato B series contactors.

The RFN200100 is specified as non phase-failure and non single-phase sensitive and supports manual or automatic resetting. Its Class 10A thermal tripping characteristic, integrated test button and trip indicator provide practical functionality for motor starter commissioning, operation and maintenance.

With a rated operational voltage of 690 V, rated insulation voltage of 1000 V and rated impulse withstand voltage of 6 kV, the RFN200100 is engineered for industrial motor control systems. Screw fixing, robust power terminals and IP20 frontal protection support integration into industrial electrical panels and motor control assemblies.
