4-pole contactor, AC1-12A, 12 V coil — lifecycle at end-of-life hot
The ABB BC6-40-00-07 is a 4-pole contactor rated AC1-12A with a 12 V coil. It switches resistive loads up to 12 A in the AC1 duty class — that is the current-carrying capacity for heater banks, lighting, or transformer primaries, not motor starting. The 4-pole configuration handles three-phase plus neutral or two independent load circuits in one package.
