Why Choose the Lovato BF3800L024 Low-Consumption Power Contactor?
The Lovato BF3800L024 is a compact three-pole power contactor with a low-consumption DC coil, designed for reliable motor and load switching in industrial automation systems. Part of the Lovato BF38 series, it combines robust power-contact performance with reduced control-circuit power requirements.
Rated for an AC-3 operational current of 38 A, the BF3800L024 can control three-phase motors rated up to 18.5 kW at 400–440 V. Its long mechanical and electrical service life makes it suitable for frequently operated machinery, motor starters and automated control panels.
The contactor features a 24 V DC low-consumption coil requiring only 2.4 W during inrush and holding. Screw or 35 mm DIN-rail mounting, IP20 power-terminal protection when properly wired and a broad operating temperature range support straightforward installation in demanding industrial environments.

Efficient Control for Industrial Motor Switching
Power contactors enable motors and other electrical loads to be switched remotely by an automation controller or control circuit. The BF3800L024 uses a 24 V DC electromagnetic coil to operate its main contacts while consuming only 2.4 W, helping reduce the power demand placed on control-system power supplies.
The low-consumption coil makes this contactor particularly suitable for PLC-controlled equipment and panels containing multiple contactors. Its switching capacity, compact BF38 construction and long operating life support dependable use in direct-on-line starters, reversing starters and coordinated motor-control assemblies.
Typical Applications
- PLC-controlled machinery and automation panels.
- Three-phase motor starters and control systems.
- Industrial pumps, fans and compressors.
- Conveyors and material-handling equipment.
- Manufacturing and processing machinery.
- Control panels using 24 V DC power supplies.
