Lovato 11RFA9023 is a three-pole thermal motor protection relay with a 0.14–0.23 A adjustable current range, automatic reset and phase failure sensitivity for direct mounting on BG06, BG09 and BG12 mini-contactors.
£73.99
The Lovato 11RFA9023 is a compact and reliable thermal motor protection relay designed to protect three-phase motors against overload and phase failure conditions. Part of the Lovato 11RFA9 series, it features phase failure and single-phase sensitivity together with automatic resetting for dependable motor protection in industrial control applications.
Designed for direct mounting on Lovato BG06, BG09 and BG12 mini-contactors, the 11RFA9023 provides a space-efficient motor starter solution without requiring separate relay mounting. Its thermal release mechanism, Class 10A tripping characteristic, test button and trip indicator provide practical protection and straightforward system monitoring.
With an adjustable operational current range of 0.14–0.23 A and a rated operational voltage of up to 690 V, the 11RFA9023 is suitable for protecting small three-phase motors. Its IP20 frontal protection and robust industrial design support reliable operation in control panels and machinery applications.
Thermal overload relays such as the Lovato 11RFA9023 protect electric motors by responding to sustained overcurrent conditions that can cause overheating and equipment damage. Phase failure sensitivity provides additional protection when one phase of a three-phase supply is lost, helping reduce the risk of abnormal motor operation.
The 11RFA9023 is designed to integrate directly with compatible Lovato BG mini-contactors, creating a compact motor starter assembly. Its automatic reset function, trip indication and test facility make it well suited to industrial machinery, automation equipment and control-panel applications where dependable motor protection is required.
