Feature → Business Impact → Application: The AX32-40A block contactor features 3 main normally open contacts with 1 built-in auxiliary NC contact, enabling compact control of 3‑phase motors and power circuits up to 690 V AC. This topology reduces wiring complexity and minimizes panel footprint, delivering measurable efficiency gains on factory floors where space is at a premium. Application wise, use it in press lines, conveyors, and pump suites where fast switching and reliable motor control are essential. Feature → 24 V control circuit compatibility → Application: The coil accepts 24 V (50 Hz) and 24 V (60 Hz), simplifying integration with standard industrial control systems and PLCs. This compatibility reduces control-relay proliferation and supports consistent coil drive across machines. Feature → Thermal and switching ratings → Application: With AC-1 55 A and AC-3 up to 32 A (at common voltages), alongside a clean power loss profile (2.5 W per pole in AC-1, 0.9 W in AC-3), operators gain predictable thermal performance and energy efficiency. Feature → Build quality and certifications → Application: CE, UL/CSA, CCC declarations, RoHS/REACH compliance, and IP20 terminations ensure compliance and safer installation across multinational plants. Feature → Mechanical and electrical performance → Application: Operate times (coil de-energization to NC/NO changes) and short-circuit withstand ratings support reliable cycling in automation sequences, reducing unscheduled downtime. Feature → Modularity and accessories → Application: Front or side-mount add-on auxiliary blocks and wide accessory options allow quick adaptations to evolving control schemes without replacing the base device.

FAQs
This ABB block contactor supports front or side mounting with add‑on auxiliary blocks, enabling flexible panel layouts. The device uses screw terminals and IP20 protection, which simplifies wiring and ensures safe, reliable installation in standard control panels.
For 690 V operation, the device offers AC-1 Ie up to 55 A (with variations by temperature) and AC-3 Ie up to 21–32 A depending on voltage and configuration. These figures align with typical motor starting and running requirements in mid-power applications.
Yes. The contactor coil is rated for 24 V control circuits at 50 Hz and 60 Hz, simplifying integration with common PLCs and control cabinets without additional interface modules.
The AX32/AX40 family carries CE, UL/CSA, CCC certifications, and RoHS/REACH declarations, along with DoCs for CE compliance, supporting safe, compliant operation across markets.
Low coil power loss (2.5 W per pole in AC‑1, 0.9 W in AC‑3) reduces heat and energy use. Its modular design and wide accessory compatibility shorten downtime during upgrades, delivering faster maintenance and improved system uptime.
