The ABB AF09ZB-40-00RT-21 is a compact four-pole contactor with ring-tongue terminals designed for switching motors and power circuits in industrial and railway-related electrical systems. As part of the ABB AF contactor range, it uses electronically controlled coil technology to provide reliable operation across a wide control-voltage range.
ABB AF technology allows the contactor to operate from 24–60 V AC at 50/60 Hz or 20–60 V DC. This wide operating range helps manage control-voltage variations, reduces panel energy consumption and supports dependable switching on unstable control networks. Integrated surge protection eliminates the need for a separate external suppression component.
The AF09ZB-40-00RT-21 provides four normally open main contacts and can control three-phase motors rated up to 4 kW at 400 V AC. It can also switch AC-1 power circuits up to 25 A at 690 V, while its ring-tongue terminals support secure conductor connections in applications subject to vibration.
Contactors such as the ABB AF09ZB-40-00RT-21 provide electrically controlled switching for motors and power loads. Its four normally open main poles allow four-pole AC-1 switching or motor-control configurations, while the electronically controlled coil maintains dependable operation across a wide control-voltage range.
The contactor’s ring-tongue terminals and compliance with applicable railway equipment standards make it suitable for installations where secure electrical connections and resistance to operational vibration are important. Add-on auxiliary contact blocks and other compatible accessories can extend its functionality.
