The ABB S202-C16 (order code 2CDS252001R0164) is a two-pole miniature circuit breaker from the System pro M compact S200 range, rated 16 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: S202 = S200 series, 2 protected poles; C = tripping curve; 16 = rated current in amperes. The breaker is 2 modules wide (35 mm) and snaps onto a 35 mm DIN rail.

Typical applications
- Lighting and socket-outlet final circuits
- Small motors and fans with moderate inrush
- Resistive heating loads
- Distribution boards in commercial buildings
- Direct replacement of an ABB S202-C16 with the same order code
Compatibility and replacement
The order code 2CDS252001R0164 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 (16 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.
Can it be fed from the bottom?
Yes. ABB lists the supply direction as optional and the mounting position as any, and the twin terminals accept cable and busbar together.
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.
