NEMA Size 00, 9 A — what the ratings mean for fit
The ABB A9N00-30-10-84 is a NEMA Size 00 contactor rated 9 A continuous, 3-pole, with a 120 VAC coil. NEMA sizing is a standard frame-and-rating envelope — Size 00 is the smallest NEMA contactor frame, intended for light motor loads or resistive heating circuits up to 9 A at 600 V. The 120 VAC coil means it pulls in on a standard control transformer secondary; the coil draw is within the range a typical 120 VAC control circuit supplies without a separate interposing relay.
What ships with the contactor
The A9N00-30-10-84 includes a factory-fitted 1 N.O. auxiliary contact block on the front of the contactor. This is the standard A-Line auxiliary — it switches at the same rating as the main poles and provides a feedback signal or interlock without a separate add-on block. The contactor is non-reversing; reversing duty requires a mechanical interlock between two units.
