1SBL321074R8610

The ABB 1SBL321074R8610 (AX40-30-10-86) is a high-performance 3-pole AC contactor engineered for reliable switching and control of 3-phase motors and industrial power circuits. ABB specifies the AX32/AX40 range for power circuits up to 690 V AC, with a block-type construction, three main poles, a built-in auxiliary contact, AC-operated control circuit, and provision for additional front- or side-mounted auxiliary contact blocks.

For this particular model, AX40-30-10-86, the control coil is rated 400–415 V AC at 50 Hz / 415–440 V AC at 60 Hz. ABB catalogue data identifies the AX40 with approximately 40 A AC-3 operational current, 60 A AC-1 operational current, and 18.5 kW motor rating at 400 V AC-3, making it suitable for demanding industrial motor-control and switching applications. The “-10” configuration provides 1 built-in NO auxiliary contact, while the product uses screw terminals for secure electrical connections.
