Rating and fit
The ABB AF80-30-00-11 is a 3-pole contactor rated for 105 A at 1000 VAC, with a 20-60 VDC control coil. The 105 A rating is the continuous thermal current (Ith) — the current the main poles can carry continuously in an enclosed panel without exceeding the temperature rise limits. Surface-mount design means it bolts directly to a backplate or panel — no DIN rail adapter. Plan for M6 or M8 mounting hardware and sufficient clearance for the arc chutes above and below. The coil draws from a 20-60 VDC supply; at 24 VDC nominal the pickup voltage is around 18 V, dropout below 10 V. If your control voltage is 24 VDC, the AF80-30-00-11 holds cleanly; if you're on a 48 VDC bus, it sits in the middle of the coil range without a dropping resistor.
Coil voltage range
The 20-60 VDC control coil is a wide-band coil — it covers nominal 24 V, 36 V, and 48 VDC systems without needing a coil change. That's useful if your panel has mixed DC bus voltages or if you're standardizing on one contactor variant across multiple machine builds. The AC coil variant (24-60 V 50/60 Hz) is also available under the same order code prefix; the AF80-30-00-11 specifically is the DC coil version as listed.
