ABB AF40-30-00-11 Contactor

The ABB AF40-30-00-11 Contactor is a high-performance 3-pole electrical contactor designed for industrial and HVACR applications requiring reliable motor control. Featuring a wide 24-60V AC/DC control voltage range, this versatile component utilizes AF technology to manage voltage fluctuations and reduce energy consumption in the control circuit. Engineered for 40 amp AC-3 ratings (70 amp AC-1), it provides robust switching for motors up to 18.5 kW or 25 hp. This unit serves as the direct replacement for A40-30-10-81, offering modern electronic coil management that ensures stable operation even in unstable networks. Built with screw terminals for secure wiring, this IEC motor starter contactor minimizes humming and chatter, extending the operational life of your electrical system while maintaining compact DIN rail mounting compatibility for space-efficient installations.

• Universal Compatibility: Wide dual AC/DC coil voltage eliminates the need for multiple spare parts.
• Energy Efficiency: AF technology reduces power consumption by up to 80% compared to traditional coils.
• Seamless Integration: Compact design allows for easy DIN rail or plate mounting in crowded panels.
• High Reliability: Built to withstand significant voltage drops and surges without dropping out.

Common Questions:

What is the difference between AF40-30-00-11 and the older A40 series?
The AF40-30-00-11 features an electronically controlled coil that accepts both AC and DC voltages, whereas the legacy A40 series used dedicated AC or DC coils. It is a drop-in functional replacement for A40-30-10-81.

Can this contactor be used for both 50Hz and 60Hz systems?
Yes, the electronic AC/DC coil is designed to operate seamlessly on both 50Hz and 60Hz frequencies, as well as direct current networks.

Does this model include auxiliary contacts?
This specific model (AF40-30-00-11) is a 3-pole configuration. If your application requires additional feedback loops, auxiliary contact blocks can be mounted on the front or side.
