Why Choose the Lovato 11RFNA910 Thermal Overload Relay?
The Lovato 11RFNA910 is a three-pole thermal motor protection relay designed for direct mounting on Lovato BG06, BG09 and BG12 mini-contactors. With an adjustable operational current range of 6–10 A, it provides thermal overload protection for compatible three-phase motor control applications.
Part of the Lovato RFNA9 motor protection relay series, the 11RFNA910 features automatic resetting, a test button and a trip indicator. The relay is specified as non-phase-failure/non-single-phase-sensitive and incorporates one normally open and one normally closed auxiliary contact for integration into motor control circuits.
With a 690 V rated operational voltage, 690 V rated insulation voltage and 8 kV rated impulse withstand voltage, the 11RFNA910 is designed for industrial motor protection systems. Its Class 10A tripping characteristic and compact direct-mounting format make it suitable for motor starters built around compatible Lovato BG mini-contactors.

Thermal Overload Protection for Three-Phase Motors
Thermal overload relays protect motors against sustained overcurrent conditions that can cause excessive heating. The relay monitors motor current and, when an overload persists according to its tripping characteristic, changes the state of its auxiliary contacts so the associated control circuit can disconnect the motor.
The Lovato 11RFNA910 combines a 6–10 A adjustable current range with Class 10A tripping and automatic resetting. Direct mounting on compatible BG06, BG09 and BG12 mini-contactors enables compact motor starter assemblies for industrial machinery and control-panel applications.
Typical Applications
- Three-phase motor thermal overload protection.
- Motor starters using Lovato BG06, BG09 or BG12 mini-contactors.
- Industrial machinery control panels.
- Compact motor control assemblies.
- OEM automation and machine-building equipment.
- Industrial motor switching and protection systems requiring automatic reset.
