Why Choose the Lovato 11RFN9023 Thermal Overload Relay?
The Lovato 11RFN9023 is a compact and reliable thermal motor protection relay designed to protect three-phase motors against sustained overload conditions. As part of the Lovato 11RFN9 thermal overload relay series, it combines an adjustable current setting with manual resetting for dependable motor protection in industrial control applications.
Designed for direct mounting on compatible Lovato BG mini-contactors, the 11RFN9023 enables a compact motor starter configuration and straightforward integration into electrical control panels. Its Class 10A tripping characteristic provides thermal overload protection for motors where controlled manual resetting is required after a trip.
With an adjustable operational current range of 0.14–0.23 A, the 11RFN9023 is designed for low-current motor protection applications. The relay is non-phase-failure-sensitive and is therefore suited to installations where thermal overload protection without phase failure sensitivity is specified.

Reliable Motor Protection for Industrial Machinery
Thermal overload relays such as the Lovato 11RFN9023 protect electric motors by responding to sustained overcurrent conditions that can cause excessive heating and damage. The adjustable current setting allows the overload relay to be matched to the rated current of a compatible motor within its specified operating range.
The 11RFN9023 uses manual resetting following an overload trip and does not incorporate phase failure sensitivity. Its compact direct-mounting format makes it suitable for industrial machinery, automation equipment and motor control panels where reliable thermal overload protection is required.
Typical Applications
- Low-current three-phase motor overload protection.
- Industrial machinery and automation equipment.
- Compact motor starter assemblies.
- Electrical control panels.
- OEM machinery and control systems.
- Industrial motor control circuits requiring manual overload reset.
