The 277 V AC coil matches North American lighting panel circuits and 480Y/277 V distribution — common in commercial and light industrial control panels where a 277 V control bus feeds contactors directly without a step-down transformer. ## 30 A rating — what it means for motor and resistive loads The 30 A rating applies across the 4 poles at the 600 V rated insulation voltage. For AC-3 motor duty (squirrel-cage motors, starting and disconnecting under load), the 30 A frame typically switches motors in the 7.5–10 kW range at 400 V, but the exact motor power depends on the service factor and the application's switching frequency. The 4 NO contact arrangement means all four poles switch simultaneously — no auxiliary contacts are integrated into the base unit, so a separate auxiliary block is needed if the control circuit requires a feedback signal.","metaTitle":"A16-40-00-42 4-Pole Contactor, 30 A, 277 V Coil, EOL","metaDescription":"A16-40-00-42 4-pole IEC contactor, 30 A, 277 V AC coil, 4 NO contacts.
