Lovato RF380025 is a three-pole Class 10A thermal overload motor protection relay with a 0.16-0.25 A operational current range, phase-failure sensitivity and direct mounting on BF09-BF38 contactors.
£66.60
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.
Thermal overload relays protect motors by responding when sustained current exceeds the selected operating range. The Lovato RF380025 combines an adjustable 0.16–0.25 A current setting with phase-failure sensitivity and a Class 10A tripping characteristic to provide protection for compatible three-phase motor circuits.
Direct mounting onto Lovato BF09–BF38 contactors enables the RF380025 to form part of a compact motor starter assembly. Manual or automatic resetting, together with the integrated test button and trip indicator, supports straightforward operation, testing and maintenance.
