Why Choose the Lovato BF1810A110 Three-Pole Contactor?
The Lovato BF1810A110 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 open auxiliary contact for signalling, holding and control functions. Its 110 V AC, 50/60 Hz control coil is suitable for widely used 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 BF1810A110 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 BF1810A110’s 110 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 open auxiliary contact operates with the contactor and can be used for electrical holding circuits, operating-status feedback or interlocking. Additional compatible auxiliary blocks and accessories can be fitted when the control system requires more contacts or specialised functions.
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.
