Feature → Business Impact → Application: The 3 main normally open contacts (NO) and 1 built-in auxiliary NO contact simplify wiring and reduce panel footprint, enabling faster installation and easier fault tracing in 3‑phase motor circuits. This directly improves machine uptime and reduces wiring errors in conveyors, pumps, and machine tooling. Feature → Business Impact → Application: Rated for main and auxiliary circuits up to 690 V with AC-1 and AC-3 compatibility, allowing seamless control of high-demand motors and power circuits while maintaining predictable switching performance in heavy-duty automation. Feature → Business Impact → Application: Screw terminals and IP20 protection provide rugged, maintenance-friendly connections that resist contamination and vibration, cutting service time during panel audits and field replacements across manufacturing lines. Feature → Business Impact → Application: Compact footprint (54 mm width) and built-in auxiliary contact options support front or side mounting, enabling modular expansion and flexible integration with existing ABB AX32/AX40 contactor systems in industrial control panels. Feature → Business Impact → Application: Clear thermal and current ratings (Ith 65 A open, Ie up to 60 A at various voltages) reduce overdesign risk, enabling precise protection schemes and cost-effective motor control for HVAC, pumps, and material handling. Feature → Business Impact → Application: Comprehensive documentation and standard compliance (Ce RoHS REACH UL/CSA where applicable) streamline procurement, testing, and global deployment, lowering total cost of ownership and speeding time-to-automation.

FAQs
Yes. The device is rated for main and auxiliary circuits up to 690 V and is designed to switch 3-phase motors. It supports 50/60 Hz control voltages and offers AC-1 and AC-3 ratings suitable for a range of industrial motor applications, including conveyors and pumps.
For AC-1 operation, Ie is specified around 60 A at 240 V and 60 A at 690 V under appropriate ambient conditions. For AC-3 operation, Ie reaches about 40 A at 415 V, 37 A at 440 V, and down to 25 A at 690 V. These figures support reliable motor starting and running in typical industrial loads.
Yes. The AX32/AX40 family supports add-on auxiliary contact blocks for front or side mounting, enabling flexible control circuits and expanded signaling. Installation remains straightforward with screw-terminal connections and a compact footprint that simplifies panel design and future expansion.
This model features CE Declaration of Conformity, RoHS and REACH declarations, and a UL Certificate for related AX-series models. It also aligns with global standards for safety and environmental compliance, including applicable WEEE and CMRT considerations, ensuring international deployments meet regulatory requirements.
Choose the right mounting arrangement (front or side) with available auxiliary blocks to suit your control scheme. Use proper tightening torques: main circuit 2.3 N·m, auxiliary 1 N·m, and control 1 N·m. Regularly inspect screw terminations, maintain IP20 seals, and plan for standard electrical switching frequency limits to minimize contact wear and downtime.
