Its interrupting rating of 50 kA at 230 V AC gives substantial fault-current headroom for industrial panel applications where the prospective short-circuit current can be high. The DIN-rail mount (per EN 60715) clips directly into the standard 35 mm rail inside a distribution board or control enclosure. No adapter plate needed; it occupies three module widths (each pole one 18 mm slot).

Frequently asked questions
What is the interrupting rating of the S803S-D16?
The S803S-D16 has a 50 kA interrupting rating at 230 V AC. That is the maximum fault current it can safely interrupt under short-circuit conditions.
What does the D trip curve mean on this breaker?
The D-curve sets the magnetic trip threshold at 10–20 times the rated current (16 A). It is designed for loads with high inrush, such as motors, transformers, or discharge lighting, where a B- or C-curve would trip on startup.
Where can I buy the S803S-D16?
The S803S-D16 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
