Why Choose the Lovato BF80T2A400 Contactor?
The Lovato BF80T2A400 is a robust four-pole power contactor designed for controlling motors and other high-current electrical loads in industrial systems. As part of the Lovato BF80 contactor series, it combines two normally open and two normally closed main poles with a conventional thermal current rating of 115 A.
This contactor provides an AC-3 operational current rating of 80 A at up to 440 V and a three-phase motor rating of 45 kW at 400 V. Its 2NO+2NC main-contact configuration supports applications requiring simultaneous switching, isolation, reversing logic or electrical interlocking.
The BF80T2A400 incorporates a 400 V AC coil for 50/60 Hz operation and can be installed using screws or a 35 mm DIN rail. Its high insulation rating, IP20 terminal protection and durable construction make it suitable for industrial control panels and automated machinery.

- IP20 front power-terminal protection when correctly wired.
Reliable Switching for Motors and High-Current Loads
A power contactor uses an electrically energised coil to operate its main contacts, allowing a control circuit to switch motors and other high-current loads remotely. The Lovato BF80T2A400 provides four switching poles for applications requiring more than the conventional three normally open motor poles.
Its AC-3 rating covers squirrel-cage motor starting and switching off while the motor is running, while the AC-1 rating applies to non-inductive or slightly inductive loads. Appropriate overload and short-circuit protection must be selected for the connected equipment and installation conditions.
Typical Applications
- Industrial motor starters and control systems.
- High-current resistive and slightly inductive loads.
- Electrical interlocking and reversing circuits.
- Industrial heating systems.
- Automated production machinery.
- Electrical control panels and switchboards.
