ABB AX40-30-01-81 is a 24 V, 50 or 60 Hz contactor for electrical control applications. The model is part of ABB’s AX contactor range and is intended primarily for controlling three phase motors and power circuits. ABB describes the AX32 and AX40 contactor family as suitable for circuits up to 690 V AC, subject to specific installation requirements. This listing identifies the exact variant clearly, helping customers specify a compatible replacement or component for a professionally designed control system. It is an ABB AX40 contactor with a 24 V alternating current control supply for selected industrial control applications when specified.

The catalog designation is AX40-30-01-81; ABB product ID is 1SBL321074R8101; EAN is 3471522402813. These references make ordering, stock control, quotation preparation, and product matching more straightforward. When comparing alternatives, buyers should use the full model number and product ID rather than rely on a product image or shortened name. Exact identification is useful for maintenance teams, panel builders, distributors, and purchasing departments that need to cross check a selected contactor against project documentation. Retaining the identifiers in an order also helps distinguish this 24 V, 50 or 60 Hz version from AX40 variants with different configurations or distinct coil supplies.

ABB describes the AX32 and AX40 contactors as block type devices with three main poles and one built in auxiliary contact. Separately ordered auxiliary contact blocks support front or side mounting, allowing an installation to be adapted when more contacts are needed. This arrangement gives designers a starting configuration and an option to extend auxiliary signaling or interlocking functions through compatible accessories. Any accessory, connection method, protective device, or operating arrangement should be confirmed against current ABB documentation and the requirements of the electrical system. The product is supplied as the stated contactor model; specify additional components separately when required.

The ABB AX40-30-01-81 is an industrial contactor with a 24 V, 50 or 60 Hz control supply, three main poles, and one built in auxiliary contact. Its intended use includes control of three phase motors and power circuits within the manufacturer’s stated family voltage scope. The reference information makes it easier to place the component in a bill of materials, procurement list, or maintenance record. The product photo is a visual guide; the official model number, product ID, and approved technical documentation remain the basis for final selection. This approach supports accurate communication across engineering, purchasing, installation, and service teams.
