Why Choose the Lovato BF40T4A048 4-Pole Power Contactor?
The Lovato BF40T4A048 is a robust four-pole power contactor designed for reliable switching of industrial electrical loads, machinery and automation systems. Part of the Lovato BF40 series, it features four normally open main contacts and provides an AC-1 operational current rating of 70 A at 400 V AC.
In addition to its AC-1 capability, the BF40T4A048 provides an AC-3 operational current of 40 A at 400 V AC and a corresponding three-phase motor rating of 18.5 kW. Its four-pole configuration makes it particularly useful where an additional conductor must be switched alongside a three-phase circuit, as well as for resistive loads, heating equipment and general industrial power switching.
This specific BF40T4A048 version uses a 48 V AC, 50/60 Hz control coil. With screw-type frame-clamp power terminals, IP20 front protection, a mechanical life of up to 15 million cycles and compatibility with screw or 35 mm DIN rail mounting, it provides a practical solution for industrial control-panel installations.

Reliable Four-Pole Switching for Industrial Automation
The Lovato BF40T4A048 provides electromagnetic control of industrial power circuits from a lower-power 48 V AC control signal. Energising the coil closes all four normally open main contacts simultaneously, allowing PLCs, control relays and automated machinery to switch substantial electrical loads without carrying the load current through the control equipment.
Its combination of a 70 A AC-1 rating, 40 A AC-3 rating at 400 V and four-pole architecture makes the BF40T4A048 suitable for both general-purpose power switching and motor-control duties. The fourth pole can also accommodate applications requiring an additional switched conductor alongside a three-phase circuit.
Typical Applications
- Industrial electric heating and resistive load control.
- Four-pole industrial power switching.
- Three-phase circuits requiring an additional switched conductor.
- Motor starters and industrial machinery.
- HVAC, pumps and ventilation systems.
- Industrial switchboards and control panels.
- Conveyors and material handling equipment.
- OEM machinery and automation systems.
