£126.10
The ABB AF16Z-40-00-21 (SKU: 1SBL176201R2100) is a compact and highly reliable 4-pole contactor designed for switching motors and power circuits in industrial automation, HVAC equipment and electrical control panels. As part of the trusted ABB AF contactor series, it incorporates ABB's advanced electronic coil technology to ensure dependable operation even under fluctuating control voltages.
The integrated AF wide-range electronic control coil operates from a 24-60 V AC (50/60 Hz) or 20-60 V DC supply, allowing one contactor to cover multiple control voltages while reducing panel energy consumption. Built-in surge suppression eliminates the need for external suppressors, simplifying installation and improving long-term reliability.
With a 4-pole normally open (4NO) configuration, a 690 V IEC rated operational voltage and the ability to control motors up to 7.5 kW at 400 V AC (AC-3), the AF16Z-40-00-21 is ideal for industrial machinery, pumps, compressors, HVAC systems and power distribution applications.
The ABB AF16Z-40-00-21 delivers dependable switching performance for industrial motors and electrical loads while maintaining reliable operation across a wide range of control voltages. Its electronically controlled coil reduces holding power consumption, extends service life and improves the efficiency of modern control panels.
Designed for machine builders, panel manufacturers and maintenance engineers, the AF16Z contactor offers flexible installation, excellent durability and seamless integration into industrial automation systems.
