Key ratings — 30 A, 4-pole, 120 VAC coil
The A16-40L-00-84: Rated 30 A continuous, 4-pole configuration, with a 120 VAC control coil. This is an electrically held, open-type lighting contactor in the ABB A-Line series, A16 frame, rated for 600 VAC. The 30 A rating governs the connected lighting load per pole — derate for ambient temperature per IEC 60947-4-1 if the panel ambient exceeds 40 °C.
Panel fit and mounting — open-type, not a DIN-rail drop-in
This is an open-type contactor — no enclosure, no DIN-rail base. It mounts via the A16 frame's own screw holes to a backplate or subpanel. The 4-pole footprint is wider than a standard 3-pole contactor; verify panel cutout and wiring clearance before committing.
