Why Choose the Lovato 11BG0901A400 Three-Pole Contactor?
The Lovato 11BG0901A400 is a compact and reliable three-pole power contactor designed for controlling AC motors and other electrical loads in industrial machinery, automation systems and building services. As part of the Lovato BG09 series, it combines motor-switching performance with a space-efficient format for electrical control panels.
This contactor has three normally open main poles and an integrated 1NC auxiliary contact with mirror-contact function. Its screw terminals provide straightforward wiring, while the option of screw or 35 mm DIN-rail mounting supports flexible panel construction.
With an AC-3 operational rating of 9 A and 4 kW at 400 V, the 11BG0901A400 is suitable for switching small three-phase motors. Its coil operates from a 400 V AC, 50/60 Hz supply, while the contactor provides a conventional free-air thermal current rating of 20 A.

Reliable Motor Switching for Industrial Machinery
A contactor uses an electromagnetic coil to open and close its main power contacts. Applying 400 V AC to the coil energises the Lovato 11BG0901A400, closing its three main poles and supplying power to the connected load.
The built-in normally closed auxiliary contact can provide control feedback or electrical interlocking. Its mirror-contact function indicates the state of the main normally open contacts when incorporated into an appropriately designed control circuit.
Typical Applications
- Three-phase motors rated up to 4 kW at 400 V.
- Industrial pumps, fans and compressors.
- Conveyors and material-handling equipment.
- Packaging and production machinery.
- HVAC and building-services equipment.
- OEM motor-control panels and automation systems.
