ABB 4-Pole Contactor A9-40-00

Description

The ABB A9-40-00 is a robust 4-pole contactor from the reliable A-line series. It is designed for switching motor loads up to 15 kW (at 400V AC-3) and other resistive or slightly inductive loads. Its key feature is the wide-range electronic coil, which operates on any voltage from 100V to 250V in both AC and DC systems, providing excellent flexibility and reducing inventory needs. This makes it a versatile component for various industrial automation and control applications.

FAQ

Question? Can this A9-40-00 contactor be used on a DC circuit for the main poles?

Answer

While the coil is AC/DC compatible, the main poles are primarily rated for AC applications (AC-1 and AC-3). For DC switching applications (DC-1, DC-3, DC-5), you must consult the ABB technical datasheet for specific derating factors and connection instructions, as DC arcs are harder to extinguish than AC arcs.

Question? What is the main advantage of the electronic coil in this A9 series contactor?

Answer

The wide-range electronic coil (100-250V AC/DC) offers significant flexibility. It reduces inventory by covering multiple standard voltages with a single model, ensures silent operation, and has a lower power consumption compared to conventional laminated magnet coils. It also provides better performance in areas with unstable voltage supply.

Question? Are overload relays from the newer AF series compatible with this A-line contactor?

Answer

No, direct mounting of overload relays is typically series-specific. You should use an overload relay designed for the A9…A40 contactor frame size, such as the TA25DU or TA42DU series from ABB. While separate panel mounting is possible, direct connection requires mechanical compatibility.
