The ABB S803S-C50 is a 3-pole miniature circuit breaker from the S800S series, rated for 50 A continuous current with a Trip Curve C characteristic. Curve C trips between 5 and 10 times rated current (250–500 A magnetic trip), which suits moderate inrush loads like small motor starters, lighting banks, and transformer primaries. On a DIN-rail panel, the 3-pole footprint occupies three module widths; plan for the same pitch as other S800S breakers.
50 kA at 230 VAC. That is the maximum fault current the breaker can safely interrupt without damage.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Curve C means the magnetic trip activates between 5 and 10 times the rated current (250–500 A for the 50 A version), making it suitable for moderate inrush loads like small motors and lighting.
