ABB 1SBL321001R8032 A40 2-Stack 3-Pole Contactor

Description

• The ABB 1SBL321001R8032 A40 contactor is a versatile electrical device primarily designed for controlling 3-phase motors and power circuits with a voltage rating of up to 690 V AC or 220 V DC. This contactor belongs to the ABB A series and features a 2-stack design with 3 poles in the first stack and 4 built-in auxiliary contacts in the second stack. The main poles and auxiliary contact blocks are of the block type design.

• The contactor's first stack includes 3 main poles and 1 built-in auxiliary contact. The second stack is equipped with 4 built-in auxiliary contacts. Additionally, side-mounted add-on auxiliary contact blocks are available, and the built-in auxiliary contact elements are mechanically linked. This design configuration allows for flexible customization and expansion, enabling the addition of auxiliary contacts for enhanced control or signaling functions within the circuit.

• The A40 contactor is AC operated and utilizes a laminated magnet circuit for reliable and efficient performance. It is suitable for various applications beyond motor control, including isolation, capacitor switching, and lighting.
