Why Choose the Lovato 11RFN9015 Thermal Overload Relay?
The Lovato 11RFN9015 is a compact and reliable thermal motor protection relay designed to protect three-phase motors against overload conditions. As part of the Lovato 11RFN9 motor protection relay series, it features a non-phase-failure-sensitive design and manual resetting for controlled motor protection in industrial applications.
Designed for direct mounting on Lovato BG06, BG09 and BG12 mini-contactors, the 11RFN9015 enables a compact motor starter assembly while simplifying control-panel installation. Its Class 10A tripping characteristic and manual reset function make it suitable for applications where an overload trip should require deliberate operator intervention before restarting the motor.
With an adjustable operational current range of 0.09–0.15 A and a maximum rated operational voltage of 690 V, the 11RFN9015 is designed for low-current three-phase motor circuits. Its IP20 frontal protection, screw-terminal connections and compact direct-mounting format support reliable integration into industrial machinery and automation systems.

Reliable Motor Protection for Industrial Machinery
Thermal overload relays such as the Lovato 11RFN9015 protect electric motors by responding to sustained overcurrent conditions that can cause excessive heating and equipment damage. The adjustable current setting allows the relay to be matched to the protected motor within its specified operating range.
The 11RFN9015 is designed for applications that do not require phase failure sensitivity and uses manual resetting after an overload trip. Its direct compatibility with Lovato BG06, BG09 and BG12 mini-contactors allows compact motor starter assemblies to be created for industrial machinery, automation equipment and electrical control panels.
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.
- Motor circuits using Lovato BG06, BG09 or BG12 mini-contactors.
