Contactor AF16-30-10 3P BOB 24-60VAC 20-60VDC

The ABB AF16-30-10-11 contactor, reference 1SBL177001R1110, is a three-pole contactor from the AF range designed for the control of three-phase motors and other electrical loads in industrial installations, electrical panels, automation systems, and switching applications. It features 3 normally open main contacts, an integrated 1NO auxiliary contact, and an electronic coil capable of operating on both alternating current and direct current.

This model supports a control voltage of 24 to 60 V AC at 50/60 Hz and 20 to 60 V DC. Thanks to the electronic coil interface, the contactor can operate within a wide control voltage range, making it easier to integrate into installations with different control voltages and providing greater tolerance to supply variations.

Contactor for motors up to 7.5 kW at 400 V

The ABB AF16-30-10 is especially suitable for switching three-phase motors. In AC-3 duty category, it supports an operating current of 18 A at 380/400 V and motor power up to 7.5 kW at 400 V. At 415 and 440 V, it can operate motors up to 9 kW, according to ABB's specified values.

In AC-1 duty category, intended for non-inductive or slightly inductive loads, it reaches a rated current of 30 A at 690 V with ambient temperatures up to 60 °C. These performance levels make it suitable both for switching motors and for different electrical loads within control and distribution panels.

Electronic coil for AC and DC

One of the main features of ABB AF range contactors is their electronically controlled coil. In this version, identified by the -11 suffix, the coil accepts voltages from 24 to 60 V AC at 50/60 Hz and from 20 to 60 V DC.

The wide operating range allows the same contactor to be used with different control voltages without needing to replace the coil. This technology also helps maintain operation despite fluctuations in control voltage, making it especially practical in automation systems and machinery where supply stability may vary.

Integrated surge protection

The AF16-30-10 includes factory-fitted surge protection in the coil circuit. As a result, ABB eliminates in many applications the need to install an additional surge suppressor associated with the contactor, simplifying electrical panel wiring and reducing the number of required components.

This feature is especially useful in control circuits where repetitive switching can generate electrical disturbances when inductive loads are connected or disconnected.

Integrated 1NO auxiliary contact

In addition to the three main contacts, the contactor includes one integrated normally open auxiliary contact. This contact can be used for signaling functions, interlocking, contactor status feedback, or integration with other control circuit elements.

The AF series also supports additional auxiliary blocks installed on the front or side, allowing the system configuration to be expanded when the application requires a greater number of auxiliary contacts.

Operating currents and power ratings

• AC-3 at 220/230/240 V: 18 A, up to 4 kW.
• AC-3 at 380/400 V: 18 A, up to 7.5 kW.
• AC-3 at 415 V: 18 A, up to 9 kW.
• AC-3 at 440 V: 18 A, up to 9 kW.
• AC-3 at 500 V: 15 A, up to 9 kW.
• AC-3 at 690 V: 10.5 A, up to 9 kW.
• AC-1 at 690 V and 40 °C: 30 A.
• AC-1 at 690 V and 60 °C: 30 A.
• AC-1 at 690 V and 70 °C: 26 A.

Connections via screw terminals

The ABB AF16-30-10 uses screw terminals for the main circuit as well as the auxiliary and control circuits. The main circuit accepts rigid conductors up to 6 mm², as well as different flexible conductor configurations depending on the terminal type used.

The main, auxiliary, and coil terminals have an IP20 protection rating according to IEC 60529, helping protect against accidental contact with live parts during intended use inside electrical enclosures and panels.

High switching frequency

The contactor is designed for applications requiring frequent operations. ABB specifies a maximum electrical switching frequency of up to 1,200 cycles per hour in AC-3 category and a maximum mechanical switching frequency of up to 3,600 cycles per hour, always within the manufacturer's stated operating conditions.
