[faq question=”What is the ABB AF40-30-00-13 contactor used for?”]
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.
[/faq]

[faq question=”What is the control voltage range of the AF40-30-00-13?”]
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.
[/faq]

[faq question=”What are the rated operational currents and power ratings?”]
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.
[/faq]

[faq question=”Which standards and certifications does the ABB AF40-30-00-13 comply with?”]
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.
[/faq]

[faq question=”What are the mounting and wiring options for the AF40-30-00-13?”]
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.
[/faq]

[faq question=”Does the AF40-30-00-13 include built-in surge protection?”]
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.
[/faq]

[faq question=”What are the mechanical and electrical endurance ratings?”]
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.
[/faq]

[faq question=”Where can I purchase the ABB AF40-30-00-13 contactor?”]
It is available through Shansen Enterprises, an authorized ABB channel partner serving Tamil Nadu with pan-India delivery and quick WhatsApp quotations.
