Motor load capacity and coil voltage
The A16-30-10-42 is a 3-pole IEC contactor rated for 17 A motor current (AC-3 duty) and 30 A general-purpose current (AC-1). The 277 V AC coil voltage matches common lighting and HVAC control circuits — verify the control transformer secondary before wiring.
Panel fit and auxiliary contact
Built on the ABB A16 frame, the contactor includes one normally-open auxiliary contact block (1 N.O.) for feedback or interlocking. The 3-pole main contact set handles motor loads up to 17 A; the auxiliary contact is rated for control-circuit switching at the same coil voltage.
