Why Choose the Lovato 11RFNA9015 Thermal Overload Relay?
The Lovato 11RFNA9015 is a compact and reliable thermal motor protection relay designed to provide overload protection for three-phase motors in industrial control and automation applications. As part of the Lovato 11RFNA9 motor protection relay series, it combines adjustable thermal protection with automatic resetting and direct integration with compatible Lovato BG series mini-contactors.
This three-pole thermal overload relay provides dependable protection for low-current motor circuits while offering automatic reset functionality following an overload trip. An integrated test button and trip indicator assist commissioning and fault identification, while the compact direct-mounting design helps minimise space requirements within motor starter assemblies.
With an adjustable operational current range of 0.09–0.15 A and a rated operational voltage of 690 V, the 11RFNA9015 is designed for low-current three-phase motor protection. The relay mounts directly on Lovato BG06, BG09 and BG12 mini-contactors, making it suitable for compact industrial control panels and OEM machinery.

Reliable Motor Protection for Industrial Applications
Thermal overload relays such as the Lovato 11RFNA9015 respond to sustained overcurrent conditions in motor circuits. When an overload exceeds the selected operating-current setting for the required period, the relay trips the associated control circuit, helping protect the motor and connected equipment against damaging overload conditions.
The 11RFNA9015 combines a low 0.09–0.15 A adjustment range with automatic resetting, class 10A tripping and direct compatibility with Lovato BG06, BG09 and BG12 mini-contactors. These characteristics make it a practical solution for compact motor starters and low-current industrial motor protection applications.
Typical Applications
- Low-current three-phase motor starters.
- Industrial machine control panels.
- Compact motor control assemblies.
- Production and processing machinery.
- OEM automation equipment.
- Industrial electrical control systems using Lovato BG mini-contactors.
