Why Choose the Lovato BF420T4E110 4-Pole Power Contactor?
The Lovato BF420T4E110 is a heavy-duty 4-pole power contactor designed for reliable switching of high-current electrical loads in industrial control, power distribution and automation systems. As part of the Lovato BF contactor series, it combines substantial power-switching capability with an electronically controlled coil that can operate from either AC or DC control supplies.
The BF420T4E110 has an IEC conventional free-air thermal current (Ith) rating of 630 A and an AC-1 operational current rating of 600 A at up to 40 °C. Its four normally open main contacts allow simultaneous switching of four power conductors, making the contactor suitable for demanding resistive-load, heating, distribution and industrial power-control applications.
For motor-control duties, the contactor is rated at 420 A in AC-3 duty at up to 440 V and supports motors up to 200 kW at 400 V AC. The electronically controlled 60–130 V AC/DC coil provides a wide control-voltage range and allows the same contactor to be integrated into either AC or DC control circuits.

Reliable High-Current Switching for Industrial Control
Power contactors such as the Lovato BF420T4E110 allow relatively low-power control circuits to switch substantial electrical loads safely and repeatedly. Its four-pole arrangement makes it particularly suitable where four power conductors need to be controlled together, while its high AC-1 and AC-3 ratings support both resistive-load and motor-control duties.
The BF420T4E110 also features an electronically controlled coil with a broad 60–130 V AC/DC operating range. This flexible coil design simplifies integration into industrial control panels by allowing operation from either AC or DC control supplies while retaining the robust switching performance of the Lovato BF420 platform.
Typical Applications
- High-current industrial power switching systems.
- Resistive heating and AC-1 load control.
- Large industrial motor control systems.
- Electrical distribution and switchgear assemblies.
- Industrial machinery and automation panels.
- HVAC and building-services equipment.
- OEM machinery and process-control systems.
