Why Choose the Lovato 11RFA9015 Motor Protection Relay?
The Lovato 11RFA9015 is a three-pole thermal motor protection relay designed to protect three-phase motors against overload and phase-failure conditions. Its adjustable operational current range of 0.09–0.15 A enables accurate protection of low-current motor circuits.
This phase-failure-sensitive relay features automatic resetting, tripping class 10A, a test button and a visible trip indicator. One normally open and one normally closed auxiliary contact are included for signalling and integration with control circuits.
The 11RFA9015 mounts directly onto Lovato BG06, BG09 and BG12 mini-contactors, supporting compact motor starter assemblies. Its 690 V rated operational voltage, IP20 frontal protection and broad operating-frequency range make it suitable for industrial control panels and machinery.

Reliable Automatic-Reset Motor Protection
Thermal motor protection relays monitor the current supplied to a motor and trip when a sustained overload creates a potentially damaging condition. Phase-failure sensitivity adds protection when one phase is lost, helping reduce the risk of motor overheating and premature equipment failure.
The Lovato 11RFA9015 combines an adjustable current setting with automatic reset, auxiliary signalling contacts and direct contactor mounting. Automatic-reset operation should be used only where the control system and machine safety design prevent unexpected or hazardous restarting.
Typical Applications
- Protection of low-current three-phase motors.
- Motor starters requiring automatic relay resetting.
- Motor starters using Lovato BG06 mini-contactors.
- Motor starters using Lovato BG09 mini-contactors.
- Motor starters using Lovato BG12 mini-contactors.
- Industrial machinery and automation systems.
