Why Choose the Lovato BF420T4D024 4-Pole Power Contactor?
The Lovato BF420T4D024 is a heavy-duty 4-pole power contactor designed for reliable switching of high-current electrical loads in industrial control, distribution and automation systems. As part of the Lovato BF contactor series, it combines a robust power switching design with a 24 V DC control coil for integration into modern electrical control systems.
With an IEC conventional free-air thermal current (Ith) rating of 630 A, the BF420T4D024 is suitable for demanding AC-1 applications such as resistive loads, heating systems and power distribution circuits. Its four main poles allow simultaneous switching of four conductors, while the BF420 platform also provides substantial AC-3 motor-switching capability.
The contactor has an AC-1 operational current of 600 A at up to 40 °C and an AC-3 operational current of 420 A at up to 440 V. At 400 V AC it supports AC-3 motor loads up to 200 kW, while its 24 V DC coil makes it suitable for control panels using low-voltage DC control circuits.
