Three main NO contacts and no NC contacts simplify motor control, reducing panel complexity and wiring time while delivering reliable 3‑phase switching for conveyors, pumps, and fans. The business impact is lower installation costs and improved reliability in demanding environments, with clear compatibility for AC‑3 duty at up to 690 V. The coil voltage is 105 V at 50 Hz and 110–127 V at 60 Hz, ensuring regional compatibility and flexible integration with common control circuits in automation panels across global sites. The device features a rated insulation voltage of 690 V and a thermal current (Ith) of 100 A, enabling robust performance in thermal environments and reducing the risk of nuisance trips during heavy load starts. With 5 W power loss per pole in AC‑1 and 1.3 W per pole in AC‑3, energy efficiency is improved and heat generation is kept within panel design limits. The compact footprint (82 mm wide, 110 mm deep, 108 mm high) and a weight of 1.05 kg support space‑constrained installations in machine control cabinets. Screw terminals simplify wiring and maintenance, while the option to add auxiliary contact blocks provides scalable control logic without replacing the base device. This combination aligns with industry standards and CAD workflows, streamlining spare parts planning and field upgrades for contract manufacturers and system integrators. The unit’s IP20 protection class and wide operating temperature range (-25 to 55 C with thermal overload relay) help ensure dependable performance in typical industrial environments and reduce the need for frequent maintenance. With 3 NO main contacts and no NC contacts, the AX50‑80A family’s modular design supports straightforward expansion and easier spare parts management, reducing total cost of ownership when upgrading legacy systems. The device’s documentation set, including a data sheet, CAD drawings, and installation instructions, accelerates the commissioning process and minimizes risk during startup. This makes the ABB contactor an ideal choice for panel builders seeking predictable performance and quick time‑to‑value in motor control applications.

FAQs
Install with the screw terminals provided for the main and control circuits. Ensure the coil voltage matches your supply (105 V at 50 Hz or 110–127 V at 60 Hz). Tighten control circuit terminals to 1 N·m and main circuit terminals to 4 N·m. If needed, add an auxiliary contact block to expand control logic, then verify IP20 protection and cooling conditions to prevent overheating.
The coil operates at 105 V for 50 Hz and 110–127 V for 60 Hz. This enables compatibility with regional control circuits in global installations, reducing the need for additional power converters or relays.
Rated operational current AC‑3 is up to 35 A at 690 V (55 °C) and up to 50–53 A at lower voltages per table. Maximum breaking capacity at 690 V is 630 A cos φ 0.45, enabling robust motor start‑up for common industrial loads.
Yes. The device carries CE and UL certifications with RoHS compliance, and ABB provides the associated DoCs and declarations to support manufacturer and safety compliance in international installations.
