It's designed for branch circuit protection in industrial control panels, typically feeding motor starters, welding equipment, or transformer loads where high inrush currents are expected — the D-curve holds through the start-up surge and trips on sustained overloads or short circuits.

Frequently asked questions
Where can I buy the S803N-D100 and how is it quoted?
The S803N-D100 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or lead-time figure is published here.
What is the S803N-D100's weight?
The listed weight is 0.20 kgs — light enough for standard DIN-rail mounting without additional support.
Will the S803N-D100 drop into a panel specified around the SH203T-C40?
Mechanically, yes — both are DIN-rail mount miniature MCCBs with similar footprint. The functional difference is the D-curve vs C-curve and the 100 A vs 40 A rating, so verify the branch circuit's inrush and continuous current before swapping.
