I. AF Series – Electronic Coil Control Technology
The AF series is ABB's high-end flagship product, with its core technology being an electronic control coil, bringing revolutionary changes compared to traditional contactors. If you require high reliability and global compatibility, this series is the first choice.
1. Core advantages: Wide voltage range and low power consumption
Ultra-wide voltage range:This is the most distinctive feature of the AF series.A single contactor coil can cover AC/DC voltages ranging from 24V to 500V. The product range is extremely wide, offering both 3-pole and 4-pole options. This means that regardless of whether the power supply is AC or DC, in China, the US, or Europe, a single model can be used, greatly simplifying selection and inventory management. For example, model number... AF116-30-00B-34The control voltage range is as high as 250-500V 50/60Hz and DC.
Extremely low power consumption:Compared with traditional contactors, the AF series coilsEnergy consumption reduced by approximately 80%.This not only saves energy but also significantly reduces heat generation inside the cabinet, extending the equipment's lifespan.
Voltage sag resistance:The electronic coil design can effectively cope with instantaneous fluctuations or drops in grid voltage, ensuring that the contactor does not trip unexpectedly and guaranteeing production continuity.
AC/DC compatible:A single coil is compatible with both AC and DC power supplies, making it highly flexible in use.

Please note: The AF series also has a type in the low current range (AF09-AF38).Z-type coil(e.g., AF09Z-30-10-21) Its coil power consumption is extremely low and it can be directly driven by a PLC (24V DC, 500mA), making it very suitable for control systems that need to be directly connected to the PLC output module.
AF Series Model Naming Rules Explanation
To better understand the model number, the model code is broken down and explained here. Taking AF40-30-00-11 as an example:
AF40:Product series and frame current. This indicates the AF series, with a frame current of 40A.
30:Main contact configuration. The first digit 3 indicates the number of poles (3 poles). The second digit 0 indicates the number of NO (normally open) main contacts; 0 means no auxiliary contacts (for the number of auxiliary contacts, please refer to subsequent fields).
00:The type and quantity of auxiliary contacts installed at the factory. The first digit indicates the number of NO (normally open) auxiliary contacts, and the second digit indicates the number of NC (normally closed) auxiliary contacts. For example, 10 indicates 1 NO auxiliary contact; 01 indicates 1 NC auxiliary contact; 00 indicates no auxiliary contacts.
11Coil specification code. This code corresponds to the specific coil voltage range and control method. For example, 11 usually corresponds to a wide voltage coil of 100-250V AC/DC; 34 may correspond to 250-500V AC/DC.
II. Detailed Subdivision of AF Series Models
Subdivided by current frame size
The AF series contactors can be clearly divided into four main groups according to their design platform and application scenarios, and each group has different characteristics.

Subdivided by number of extrema
The AF series also offers different numbers of main contact poles to suit different circuit requirements.
3-pole:Standard model, used to control typical three-phase motors or circuits. The model code is usually represented by 30 (e.g., AF09-30-...).
4-pole: Used in circuits requiring simultaneous switching of the neutral line (such as lighting distribution) or for controlling single-phase loads. Model codes are typically indicated by 40 (e.g., AF26-40-...). Some 4-pole models have the following main contact configuration:2NO+2NC(e.g., AF26-22-00-13) provides a more flexible circuit design solution.
Comprehensive Attachments and System Solutions
ABB contactors' modular design allows them to be easily combined into various motor starting solutions:
Overload protection:MatchingTF series(Bimetallic) orEF series(Electronic) thermal overload relays provide overload and phase loss protection with different tripping levels such as CLASS 10, 20, and 30.
Motor starting scheme:With the help of a dedicated connection kit, it can be quickly and safely assembled intoDirect start,Reversible startandStar-delta (Y-Δ) startThe device saves assembly time and cabinet space.
Auxiliary and extended functions:It can be equipped with front-mounted or side-mounted 1-pole, 2-pole, and 4-pole auxiliary contact blocks, as well as electronic timers and other accessories to expand its functions.
How to quickly select the right model based on parameters?
If you want to select the right model based on specific parameters, ABB provides a very useful online AF contactor selection tool. You can quickly locate the model using the following path:
1. Determine the motor power or operating current:The main circuit current is determined based on either AC-3 (motor starter) or AC-1 (resistive load).
2. Determine the coil control voltage:The AF series allows you to specify a voltage range, such as 100-250V AC/DC.
3. Determine the auxiliary contact point requirements:How many pairs of NO/NC auxiliary contacts are needed?
2. Determine the number of extremes:Do you need 3 poles or 4 poles?
By combining the above information, you can obtain the complete model number.
Summarize:The AF series covers the full range from 9A to 2050A and is currently the mainstay for new project design.
