Product details

What this D-curve 40A means on the line

For a 40 A pole, that is 400–800 A instantaneous trip threshold, sized for downstream inductive loads, not resistive heaters.

For volume or scheduled releases, a blanket order with release dates typically secures better pricing — how many you want.

Frequently asked questions

Who supplies S803C-D40 and how is it quoted for volume purchases?

The S803C-D40 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time. For volume or scheduled releases, a blanket order typically secures better pricing — price drops with quantity.

Will S803C-D40 drop into a panel that was specified around S273-K40A without rewiring?

Not without DIN-rail re-spacing. The S803C-D40 is a 3-module (54 mm wide) unit at 0.91 kg, while the S273-K40A is a 2-module (36 mm) unit at 0.45 kg. The S803C-D40 occupies one extra DIN position per pole, so the rail layout must be adjusted.

What compliance documentation does ABB provide for S803C-D40?

ABB provides the standard S800C series documentation package including the datasheet, installation instructions, and declaration of conformity for IEC/EN 60898-1 and IEC/EN 60947-2. RoHS and REACH compliance statements are available on request from the manufacturer.
