Why Choose the Lovato RF380025 Motor Protection Relay?
The Lovato RF380025 is a three-pole thermal overload motor protection relay designed to protect three-phase motors against overload and phase failure conditions. Part of the Lovato RF38 range, it provides an adjustable operational current range of 0.16–0.25 A and mounts directly onto compatible Lovato BF contactors.
The RF380025 is phase-failure sensitive and supports manual or automatic resetting, allowing the reset method to be selected for the application. An integrated test button and trip indicator assist commissioning and fault diagnosis, while its Class 10A tripping characteristic provides thermal overload protection for motor circuits.
With a rated operational voltage and insulation voltage of 690 V, a 6 kV rated impulse withstand voltage and IP20 frontal protection, the RF380025 is designed for industrial motor control installations. Direct mounting on BF09–BF38 contactors provides a compact motor starter arrangement.
