ABB AF38-30-00-11 contattore, 38 A, tripolare, 3 NO, bobina 24-60 V AC / 20-60 V DC

Industrial motor control demands a contactor that combines reliable switching, compact dimensions, and flexible coil voltage options. The ABB AF38-30-00-11 contactor answers that need with a robust design rated for 38 A (AC-3) and 18.5 kW at 400 V, making it ideal for controlling three-phase motors up to 18.5 kW. Its wide-range electronic coil accepts 24-60 V AC (50/60 Hz) or 20-60 V DC, simplifying panel design and reducing inventory. With three normally open main poles and no auxiliary contacts, it provides straightforward switching for motor starting, heating, lighting, and other industrial loads.

Who is it for

This contactor is intended for panel builders, system integrators, and maintenance engineers who need a dependable, space-saving switching solution for motor control, HVAC, pumping, and general industrial automation. It suits applications where a wide coil voltage range, high electrical endurance, and compliance with international standards are essential.

Tips

To maximize service life, ensure the contactor is installed in a clean, dry enclosure with adequate ventilation. Use appropriate cable lugs and torque settings as per ABB guidelines. The wide coil voltage range allows the same contactor to be used across different control voltages, simplifying spare parts management. For motor starting, verify that the rated operational current and power match your motor's full-load characteristics.
