Why Choose the Lovato BF420T4E230 4-Pole Power Contactor?
The Lovato BF420T4E230 is a heavy-duty 4-pole power contactor designed for high-current industrial load switching, motor control and power distribution applications. Part of the Lovato BF series, it combines a conventional free-air thermal current rating of 630 A with an electronically controlled 100–250 V AC/DC coil, providing flexible integration into demanding industrial control systems.
For AC-1 resistive and general-purpose load switching, the BF420T4E230 provides a rated operational current of 600 A at temperatures up to 40 °C. It is also suitable for motor switching, with an AC-3 operational current of 420 A at up to 440 V and an AC-3 motor power rating of 200 kW at 400 V AC. Its four normally open main poles make it suitable for applications requiring simultaneous switching of four conductors.
Built for demanding industrial environments, the contactor has a 1000 V rated insulation voltage, 8 kV impulse withstand voltage and a short-time allowable current of 3360 A for 10 s. Screw mounting, a mechanical life of up to 5,000,000 operations and an operating temperature range from -40 to +70 °C make the BF420T4E230 a robust solution for high-power machinery and electrical distribution systems.

Reliable High-Current Switching for Industrial Automation
Power contactors such as the Lovato BF420T4E230 allow high-current electrical loads to be switched using a comparatively low-power control signal. Its four main contacts can simultaneously make or break four conductors, while the electronically controlled wide-range AC/DC coil provides flexible operation across different industrial control voltages.
The BF420T4E230 is suitable for both AC-1 load switching and demanding AC-3 motor applications. With a 420 A AC-3 rating and capacity for motors up to 200 kW at 400 V AC, it can be integrated into high-power motor starters, machinery, process systems and automated electrical installations where reliable repetitive switching is essential.
Typical Applications
- High-current industrial power switching.
- Three-phase motor starters and motor control centres.
- Industrial motors up to 200 kW at 400 V AC under AC-3 conditions.
- Four-pole electrical load switching systems.
- Industrial machinery and production equipment.
