ABB AF40-30-00-13 100-250V50/60HZ-DC Contactor FAQ

The ABB AF40-30-00-13 is a 3-pole contactor designed for controlling AC motors up to 18.5 kW at 400 V (AC-3 duty) or 30 hp at 480 V UL. It is suitable for switching power circuits up to 70 A (AC-1) and operates reliably on both AC and DC control voltages (100–250 V 50/60 Hz / DC). Typical uses include motor starters, power distribution panels, and automation systems.

This contactor features ABB’s AF technology, allowing a wide control voltage range of 100–250 V AC/DC at 50/60 Hz. The wide range helps maintain consistent performance even with voltage fluctuations and reduces panel energy consumption.

The AF40-30-00-13 is rated for 40 A (AC-3) at 415 V and 70 A (AC-1) at 690 V. It handles motor loads up to 18.5 kW (400 V) or 22 kW (415–690 V). The conventional free-air thermal current is 105 A at 40 °C.

It conforms to IEC/EN 60947-1 and 60947-4-1 as well as UL 60947 and CSA C22.2 standards. These certifications ensure global acceptance for industrial motor control and safety compliance.

The device supports DIN rail mounting on TH35 rails or screw mounting (2× M4 or M6). Main terminals accept 4–35 mm² cables, and control terminals handle 0.75–2.5 mm² wires. Recommended tightening torque is 4 N·m for power and 1.2 N·m for control circuits.

Yes. The contactor integrates built-in surge suppression, eliminating the need for external RC snubbers or varistors and ensuring compact, reliable operation in unstable supply networks.

The maximum mechanical switching frequency is 3600 cycles/hour, while electrical endurance (AC-3 duty) allows up to 1200 cycles/hour. Short-time withstand current is 1000 A for 1 s, and impulse withstand voltage is 6 kV.
