Why Choose the Lovato BF1801A230 Three-Pole Contactor?
The Lovato BF1801A230 is a compact and reliable three-pole AC power contactor designed for switching motors and other electrical loads in industrial machinery, automation systems and control panels. As part of the Lovato BF18 contactor series, it combines an 18 A AC-3 operational rating with dependable electromechanical performance.
This contactor features three main power poles and one built-in normally closed auxiliary contact with mirror-contact functionality. Its 230 V AC, 50/60 Hz control coil is suitable for mains-voltage industrial control circuits, while screw terminals provide secure field wiring.
With an 18 A AC-3 rating and motor capacity of 7.5 kW at 400 V AC, the BF1801A230 is well suited to switching three-phase motors in pumps, fans, conveyors and production machinery. It can be mounted on a 35 mm DIN rail or secured directly by screws.

Reliable Switching for Three-Phase Motors
An electromagnetic contactor allows a lower-power control circuit to switch a higher-power electrical load. Energising the BF1801A230’s 230 V AC coil closes its three main contacts, supplying power to the connected motor or load; removing coil voltage opens the contacts.
The integrated normally closed auxiliary contact can provide control feedback, electrical interlocking or status signalling. Its mirror-contact function supports applications where the auxiliary contact must reliably indicate the state of the main power contacts.
Typical Applications
- Direct-on-line three-phase motor starters.
- Industrial pumps, fans and compressors.
- Conveyors and material-handling systems.
- Packaging and production machinery.
- HVAC and refrigeration equipment.
- Industrial control panels and OEM automation systems.
