Rated 9 A in motor-duty (AC-3) and 21 A in general-purpose resistive (AC-1), both at 600 V. The 24 V AC coil draws from a control transformer or PLC relay output. The integrated 1 N.O. auxiliary contact block provides a feedback signal or interlock without a separate add-on. This is standard for the A9 frame — the contact block is built into the front of the contactor, not a field-installed accessory.
Deployment Context
Snap-on DIN rail mounting to a standard 35 mm rail in an enclosure or panel. The A9 frame is a compact IEC form factor — about 45 mm wide — so it fits tightly in multi-contactor groups for motor control centers or pump panels.
