Why Choose the Lovato BF15000A048 3-Pole Contactor?

The Lovato BF15000A048 is a heavy-duty three-pole BF150 power contactor designed for reliable switching of three-phase motors and industrial electrical loads. It provides an AC-3 operational current of 150 A at up to 440 V and a conventional free-air thermal current of 165 A.

This specific version uses a 48 V AC, 50/60 Hz control coil and delivers an AC-3 motor power rating of 75 kW at 400 V. Its robust BF-series construction makes it suitable for demanding motor-control panels, machinery, pumps, compressors and other high-power industrial applications.

With a rated insulation voltage of 1000 V, rated impulse withstand voltage of 8 kV and mechanical endurance of up to 15 million operating cycles, the BF15000A048 is engineered for long-term industrial service. Screw terminals and 35 mm DIN-rail or screw mounting support straightforward integration into electrical control assemblies.

Reliable High-Power Motor Switching for Industrial Machinery

Power contactors such as the Lovato BF150 provide remote electrical switching of motors and other high-current loads through an electromagnetic control coil. The BF15000A048 uses three normally open main contacts to switch three-phase circuits and is rated at 150 A AC-3, making it suitable for substantial industrial motor loads.

The 48 V AC, 50/60 Hz coil allows the contactor to integrate with compatible low-voltage industrial control circuits, while its high electrical and mechanical endurance supports frequent operation in machinery and automation systems. Robust terminals, high insulation ratings and flexible mounting options further simplify installation in professional motor-control panels.

Typical Applications

  • High-power three-phase motor starters.
  • Industrial pumps and pumping systems.
  • Compressors and refrigeration equipment.
  • Fans and ventilation systems.
  • Conveyors and materials-handling machinery.
  • Process and manufacturing equipment.
  • Industrial automation and control panels.
  • General high-current electrical load switching.
