Why Choose the Lovato BF115T4A57560 4-Pole Contactor?

The Lovato BF115T4A57560 is a heavy-duty four-pole BF115 power contactor designed for switching motors and other industrial electrical loads. It provides a conventional free-air thermal current of 160 A and an AC-1 operational current of 160 A at up to 40 °C.

This specific version incorporates a dedicated 575 V AC, 60 Hz coil. For motor-control applications, the contactor provides an AC-3 operational current of 115 A at 400 V and a corresponding three-phase motor rating of 55 kW at 400 V.

With a rated insulation voltage of 1000 V, an impulse withstand voltage of 8 kV and a mechanical endurance of up to 15 million cycles, the BF115T4A57560 is engineered for demanding industrial switching duties. It can be installed by screw fixing or on a 35 mm DIN rail, providing flexibility for machinery and control-panel applications.

Key Advantages

  • Four-pole power contactor for multi-pole industrial switching applications.
  • 160 A AC-1 operational current at ambient temperatures up to 40 °C.

High-Current Four-Pole Switching for Industrial Systems

The Lovato BF115T4A57560 uses four normally open main contacts to provide simultaneous switching across four conductors. Its 160 A AC-1 rating makes it suitable for non-inductive or slightly inductive loads, while the 115 A AC-3 rating also enables demanding three-phase motor-control applications.

The dedicated 575 V AC, 60 Hz coil makes this variant suitable for compatible industrial control supplies. High making and breaking capacities, robust power terminals and long mechanical endurance support reliable use in machinery, power distribution, automation and other installations requiring a substantial four-pole contactor.

Typical Applications

  • High-current industrial load switching.
  • Three-phase motor-control systems.
  • Four-pole power switching circuits.
  • Industrial heating and resistive loads.
  • Pumps, fans and compressor systems.
  • Machinery and production equipment.
  • Industrial automation and control panels.
  • Power distribution and electrical switching assemblies.
