The 10 A rating means it carries continuous loads up to that level without tripping, while the Curve C characteristic (5 to 10 times rated current magnetic trip) handles moderate inrush from motor starters, contactor coils, and small transformers without nuisance trips. Interrupting rating is 6 kA at 277 VAC and 10 kA at 125 VDC — sufficient for most commercial and light industrial panelboards where the available fault current stays under those thresholds. ## Panel Fit & Integration DIN-rail mount with a 3-module width (52.5 mm at 17.5 mm per pole). Spring-cage terminals accept 0.5 to 25 mm² conductors. The S200M family shares a common accessory range — shunt trip, auxiliary contacts, undervoltage release — that clip onto the right side without increasing width.","metaTitle":"ABB S203M-C10 S200M MCB, 3-Pole, 10A, Curve C, 6kA","metaDescription":"ABB S203M-C10 S200M 3-pole MCB, 10 A, Trip Curve C, 6 kA interrupting rating AC, DIN rail mount.

It will physically drop into the same panel position but changes the coordination with downstream devices."},{"question":"Where can I buy S203M-C10 and how is it quoted?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
