Why Choose the Lovato BF500T4E110 700 A 4-Pole Power Contactor?
The Lovato BF500T4E110 is a heavy-duty 4-pole power contactor designed for demanding industrial motor control and high-current power switching applications. It provides an IEC conventional free-air thermal current rating of 700 A and four normally open main power poles, making it suitable for substantial commercial and industrial electrical loads.
A key feature of the BF500T4E110 is its electronically controlled 60–130 V AC/DC coil. The wide control-voltage range allows operation from compatible AC or DC control supplies, providing flexibility when integrating the contactor into industrial machinery, motor control centres, switchboards and automated electrical systems.
The BF500T4E110 provides an AC-1 operational current of 630 A at temperatures up to 40 °C and an AC-3 rating of 500 A at up to 440 V. It also offers a 1000 V rated insulation voltage, 8 kV impulse withstand voltage, screw mounting and a mechanical endurance of 5,000,000 operations for reliable service in demanding industrial environments.

High-Current Four-Pole Switching and Motor Control
Power contactors allow substantial electrical loads to be controlled by a separate lower-power control circuit. The Lovato BF500T4E110 provides four main switching poles with an IEC conventional free-air thermal current of 700 A, an AC-1 operational current of 630 A at up to 40 °C and an AC-3 operational current of 500 A at up to 440 V.
Its four-pole configuration makes the BF500T4E110 particularly suitable where four conductors need to be switched simultaneously, while the wide-range 60–130 V AC/DC electronic coil provides flexibility for different industrial control supplies. The combination of high current capacity, substantial motor ratings and robust mechanical endurance makes it suitable for motor control centres, switchboards, machinery and automated power systems.
Typical Applications
- High-current four-pole electrical switching.
- Industrial motor control centres and switchboards.
- High-power three-phase motor control.
- Industrial machinery and production equipment.
- Resistive and inductive load switching.
- Building services and industrial automation systems.
