ABB A40-30-10 Power Contactor (Part No. 1SBL321001R8010)

ABB A40-30-10 Power Contactor (Part No. 1SBL321001R8010)

The ABB A40-30-10 is a heavy-duty, block-type 3-pole power contactor designed primarily for switching high-power circuits in industrial and commercial applications. It is part of the established ABB A-series of contactors, known for their reliability and broad application compatibility.

This contactor is engineered for controlling 3-phase motors and general power circuits, with a maximum rated operational voltage of up to 690 V AC and a high rated operational current of 40 A under AC-3 duty (motor load) at 220-240V. For resistive loads (AC-1 duty), the maximum current is 60 A

The model number provides key configuration details:

• A40 is the series and size designation.

• 30 indicates the presence of three main power poles (all Normally Open or NO).

• 10 signifies that it includes one built-in auxiliary contact (1 Normally Open or NO).

The specific part number, 1SBL321001R8010, indicates the coil voltage, which is 220–230V AC at 50 Hz and 230–240V AC at 60 Hz. The contactor uses a laminated magnet circuit and features screw terminals for secure main and auxiliary wiring.

It offers a high mechanical switching frequency of 3600 cycles per hour and is compatible with a comprehensive range of snap-on accessories, including auxiliary contact blocks, mechanical latches, and thermal overload relays, allowing it to be easily integrated into complete motor starter solutions.

In summary, the ABB A40-30-10 is a versatile, robust component for switching and controlling main power circuits, providing high current capacity and excellent modularity for various industrial control panel designs.
