The ABB S201-C10 (order code 2CDS251001R0104) is a single-pole miniature circuit breaker from the System pro M compact S200 range, rated 10 A with a C tripping characteristic. Like every S200, it is current-limiting and combines a delayed thermal release for overloads with an electromagnetic release that trips instantly at 5 to 10 x In for short circuits.
Reading the type code: S201 = S200 series, 1 protected pole; C = tripping curve; 10 = rated current in amperes. The breaker is 1 module wide (17.5 mm) and snaps onto a 35 mm DIN rail.

Typical applications
- Lighting and socket-outlet final circuits
- Machine-building control cabinets
- Small motors and fans with moderate inrush
- Control-panel supply circuits (PLC, power supplies, controls)
- Direct replacement of an ABB S201-C10 with the same order code
Compatibility and replacement
The order code 2CDS251001R0104 identifies exactly this pole count, curve and rating. Bottom-fitting auxiliary and signal contacts, shunt trips, undervoltage releases and motor operating devices from the System pro M compact range fit the S200 (accessories are sold separately). If your installation needs 10 kA breaking capacity, the S200 M version of the same rating has the same 88 x 69 mm pole size. When replacing, keep the curve (C) and rating (10 A) the circuit was designed for.
Frequently asked questions
Should I use the C curve or the D curve?
The C curve trips instantly at 5 to 10 x In; the D curve trips at 10 to 20 x In. Use C for general circuits; move to D only for loads with heavy inrush such as motors or transformers.
How many operations will it last?
ABB rates S200 breakers of 10 A at 20,000 operations (AC) electrically and 20,000 operations mechanically.
Does high ambient temperature affect it?
Yes. Per ABB, the thermal release is calibrated at 30 °C and the tripping current falls by about 6 % for every 10 K above that, so allow for it in hot panels.
