Why Choose the ABB AFS12-30-22-11 Safety Contactor?
The ABB AFS12-30-22-11, product ID 1SBL157082R1122, is a 3-pole safety contactor designed for machine safety applications where reliable switching, monitoring and control are essential. As part of the ABB AFS contactor range, it combines three normally open main contacts with permanently fitted auxiliary contacts specifically designed to support safety-related control circuits.
The AFS12-30-22-11 features three normally open main contacts together with two normally open and two normally closed auxiliary contacts. Mechanically linked and mirror contact functionality helps provide reliable contactor status monitoring, while the fixed front-mounted auxiliary contact block includes a protective cover to prevent manual operation.
With an electronic coil accepting 24–60 V AC at 50/60 Hz or 20–60 V DC, the AFS12-30-22-11 accommodates a wide control-voltage range and incorporates built-in surge suppression. It provides an AC-3 operational current of 12 A at 400 V and is rated for motors up to 5.5 kW at 400 V AC, making it suitable for safety-related motor switching and industrial machinery applications.
