ABB AF190-30-11-13 Contactor

The ABB AF190-30-11-13 Contactor is a high-performance 3-pole electrical contactor designed for heavy-duty industrial switching and motor control applications. Operating within a 100-250V AC/DC control voltage range, this versatile component features advanced AF technology that manages voltage fluctuations and reduces energy consumption in the control circuit. With a rated operational current of 190 Amps (AC-3) and a general-purpose rating up to 275 Amps, it provides robust power handling for demanding HVACR and automation systems. This unit is the direct replacement for 024-31892-000 and comes equipped with screw terminals and integrated 1 NO (Normally Open) and 1 NC (Normally Closed) auxiliary contacts for comprehensive status monitoring. Its compact design ensures efficient panel space utilization while maintaining the rugged durability required for harsh environments.

Key Benefits:

• Universal Control Voltage: The wide 100-250V AC/DC coil range simplifies inventory and ensures stable operation during voltage sags.
• Direct Compatibility: Engineered as the official replacement for model 024-31892-000, ensuring seamless mechanical and electrical integration.
• Enhanced Efficiency: AF contactor technology reduces coil energy consumption by up to 80%, lowering heat dissipation in electrical cabinets.
• Flexible Configuration: Built-in auxiliary contacts (1 NO + 1 NC) allow for immediate implementation of safety interlocks and feedback loops.
• High Load Capacity: Capable of managing 275A loads, making it suitable for large motor starting and power distribution isolation switching.

Common Questions:

What is the difference between the 190A and 275A ratings for the AF190-30-11-13?
The 190A rating refers to the AC-3 motor load capacity (up to 400V), while the 275A rating applies to AC-1 non-inductive or slightly inductive loads, such as heating elements.

Can this contactor replace older ABB EH or AF series models?
Yes, the AF190-30-11-13 is designed to replace many legacy models including the 024-31892-000. It is recommended to verify physical dimensions if replacing very old frame sizes.

Does this unit require a separate surge suppressor?
No, the ABB AF series includes built-in surge protection to handle industrial electrical noise, protecting sensitive PLC outputs without additional accessories.
