ABB AF12N0-30-10-14 NEMA Size 0 Contactor, 250-50 Coil

The AF12N0-30-10-14: NEMA Size 0 defines the physical envelope and the standard 30 A continuous rating at 600 V — this is the frame size that fits typical motor starter buckets and panel layouts for fractional-to-10 HP motors on 480 V three-phase. The 250-50 V coil taps a control transformer secondary; verify your control voltage matches that tap before wiring. The 3-pole main contacts handle three-phase motor loads; the built-in auxiliary contact block (10-14 in the code) provides one N.O. and one N.C. auxiliary for seal-in or status feedback.
