Why Choose the Lovato BF95T4A048 4-Pole Contactor?
The Lovato BF95T4A048 is a heavy-duty four-pole power contactor designed for reliable switching and control of industrial electrical loads. As part of the Lovato BF95 contactor series, it provides an IEC conventional free-air thermal current rating of 140 A in AC-1 duty, making it particularly suitable for resistive loads, heating systems, power distribution and demanding industrial switching applications.
This contactor combines high current capacity with robust electrical and mechanical performance for dependable operation in industrial control systems. Its four-pole configuration enables simultaneous switching of four conductors, while screw fixing and 35 mm DIN rail mounting provide flexible installation inside electrical panels, switchboards and machine control cabinets.
In addition to its 140 A AC-1 rating, the BF95T4A048 provides an AC-3 operational current of 95 A and a motor power rating of 55 kW at 400 V AC. A dedicated 48 V AC 50/60 Hz coil enables integration with common industrial control circuits, while the 1000 V insulation rating supports demanding power switching installations.

Reliable Four-Pole Switching for Industrial Systems
Power contactors such as the Lovato BF95T4A048 allow high-current electrical circuits to be controlled remotely through a lower-power control circuit. Energising the contactor coil changes the state of the main contacts, enabling reliable and repeatable switching of industrial loads without requiring direct manual operation of the power circuit.
The BF95T4 series is particularly suited to applications requiring four-pole switching and high AC-1 current capacity. Its robust electrical characteristics, 48 V AC control coil and flexible mounting arrangement make it suitable for switchboards, heating equipment, power distribution systems, machinery and industrial automation panels.
Typical Applications
- Industrial resistive load switching.
- Electric heating and process heating systems.
- Four-pole power distribution and isolation circuits.
- Industrial machinery and production equipment.
- Motor control and automation systems.
- Electrical switchboards and control panels.
- OEM automation and machine-building applications.
