Why Choose the Lovato M3R08012230B8 Direct-On-Line Starter?
The Lovato M3R08012230B8 is an enclosed direct-on-line (DOL) motor starter designed for switching and thermal overload protection of three-phase motors in industrial applications. It combines a contactor and adjustable thermal overload relay within an insulated enclosure, providing a complete motor-starting and protection solution.
The M3R08012230B8 is supplied with a Lovato BF8000A contactor and RF828200 thermal overload relay. The overload relay provides an adjustable current range of 60–82 A, allowing the protection setting to be matched to the rated current of the connected motor, while a dedicated RESET pushbutton provides local reset control.
With an IEC AC-3 operating rating of 80 A and 45 kW at 400 V, a 230 V AC 50/60 Hz contactor coil and IP65 frontal protection, the M3R08012230B8 provides a robust enclosed solution for fixed-speed industrial motors requiring direct-on-line starting and adjustable thermal overload protection.

Reliable Direct-On-Line Motor Starting
Direct-on-line starters provide a straightforward method of controlling fixed-speed motors by connecting the motor directly to the electrical supply through a contactor. The Lovato M3R08012230B8 combines this switching function with adjustable thermal overload protection, providing an integrated solution for starting and protecting appropriately rated industrial motors.
The 60–82 A adjustment range enables the RF828200 thermal overload relay to be configured according to the rated current of the connected motor. The integrated RESET pushbutton provides local resetting of the starter, while the enclosed construction provides IP65 frontal protection for industrial installations.
