The ABB A16-120L-00-84 is a 30 A, 12-pole electrically held lighting contactor from the A-Line series, A16 frame. It switches 12 independent lighting circuits simultaneously from a single 120 V AC control coil — common in commercial panelboards where one contactor banks multiple branch circuits for area or zone lighting control. Rated 600 V, the contactor handles line-to-line voltage for 277/480 V lighting loads without a neutral switching requirement. The 30 A per-pole rating covers most HID, LED, and fluorescent ballast loads in a single throw — no paralleling needed for a 20 A branch circuit.
Lifecycle reality — EOL hot and what that means for spares
The A16-120L-00-84 carries an EOL hot lifecycle status — the manufacturer has ended production, and remaining stock in the channel is the last available supply. For a 12-pole lighting contactor that backs up a multi-circuit zone in an existing panel, this is exactly the part to buy ahead on before it fails. Sourcing is through independent distribution — quantities are confirmed at RFQ, and the unit is quoted to order against the BOM line.
Panel fit and integration — open-type, electrically held
Open-type construction means the contactor mounts inside a panel or enclosure — no integral overmold or dead-front. The A16 frame footprint is standard for ABB's A-Line series; the 12-pole width is wider than the common 3- or 6-pole variants, so verify the DIN-rail or backplate space before committing. Electrically held (not mechanically latched) — the coil must remain energised to keep the contacts closed. This is typical for lighting contactors where a control relay or timer holds the coil during the occupied period; a power loss drops the load, which is often the intended fail-safe for lighting circuits.
