The Schneider Electric A9C15908 is an Acti9 CDS single-phase load-shedding contactor with two channels — one non-priority circuit rated at 15 A and one priority circuit adjustable from 5 to 90 A.
The priority circuit's adjustable range (5 to 90 A) lets you set the trip threshold via the 12-position rotary dial (settings: 75, 45, 20, 90, 5, 10, 30, 60, 50, 40, 15, 25 A), so you match it to the critical load's actual draw. The 12 VA power consumption is the coil's steady-state draw — negligible for the panel's control transformer budget. The operating temperature range (-5 to 55 °C) covers most control-panel environments, and the 95 % RH at 55 °C rating confirms it handles high-humidity plant floors without condensation issues.
The 90 mm width and 77 mm height fit a standard 4-module DIN-rail footprint (10 x 9 mm pitches). The screw terminals accept up to 10 mm² flexible on the non-priority side and up to 50 mm² rigid on the priority side — sized for the higher current path.
Compliant with EN 50081-1, EN 50081-2, and NF C 61-750. Depth is 60 mm, which clears most standard enclosures.
