ABB AF16 3-Pole Contactor, 1NO Auxiliary Contact, 9-16A AC-3
The ABB AF16 is a 3-pole contactor from the AF Series, available with AC-3 current ratings from 9 A to 16 A, built for controlling power circuits up to 690V AC and 220V DC. It is primarily used for switching 3-phase motors and non-inductive or slightly inductive loads. This block-type, 1-stack design includes 1 built-in auxiliary contact (1NO) and an electronic coil interface with a rated control circuit voltage of 100...250V at 50/60Hz for DC operation, letting a single coil cover a wide range of worldwide control voltages. Screw terminals simplify field wiring on commercial and industrial installations, and both 9 A and 16 A AC-3 versions share the same control-circuit, coil, and construction specifications.
Key Features
- AC-3 Current Rating: Available in 9 A AC-3 and 16 A AC-3 ratings, selectable to match the motor control circuit's power requirements.
- 3-Pole Block Design: 3 main poles plus 1 built-in auxiliary contact (1NO) in a compact 1-stack block-type configuration.
- Control Circuit: AC or DC operated electronic coil interface accepting a wide control voltage range, rated 100...250V at 50/60Hz for DC operation.
- Universal Coil Coverage: A single coil design covers 24...500V AC at 50/60Hz or 20...500V DC, allowing the same contactor to be used across different control voltages worldwide without a coil change.
- Built-In Surge Protection: Integrated surge protection eliminates the need for additional external surge suppressors.
- Terminal Type: Screw terminals for secure, straightforward field wiring connections.
- Expandable Accessories: Front and side-mounted add-on auxiliary contact blocks are available, including mechanically-linked contacts and N.C. mirror contacts for expanded control schemes.
