BF95T4E110 Lovato 4P CONTACTOR 140A AC1 110VAC/DC

Why Choose the Lovato BF95T4E110 4-Pole Contactor?

The Lovato BF95T4E110 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, machinery and demanding industrial switching applications.

This contactor combines high current capacity with an electronically controlled AC/DC coil, providing greater flexibility when integrating the device into industrial control systems. Its four normally open main poles enable simultaneous switching of four conductors, while screw fixing and 35 mm DIN rail mounting allow straightforward installation inside switchboards, electrical panels and machine control cabinets.

In addition to its 140 A AC-1 rating, the BF95T4E110 provides an AC-3 operational current of 95 A and a motor power rating of 55 kW at 400 V AC. Its wide-range electronic coil operates from 60–110 V AC/DC, while a rated insulation voltage of 1000 V and impulse withstand voltage of 8 kV support dependable operation in demanding industrial power circuits.

Reliable Four-Pole Switching for Industrial Systems

Power contactors such as the Lovato BF95T4E110 allow high-current electrical circuits to be controlled remotely through a lower-power control circuit. Energising the electronic coil closes the normally open main contacts, enabling reliable and repeatable switching of industrial loads without requiring direct manual operation of the power circuit.

The BF95T4E110 is particularly suited to applications requiring four-pole switching and high AC-1 current capacity. Its wide-range AC/DC control coil simplifies integration with different control power supplies, while its robust electrical characteristics make it suitable for switchboards, heating equipment, power distribution systems, machinery and industrial automation panels.
