- Description
With a C tripping curve and a 20 A rating, the ABB 2CSS255101R0204 SN201-C20 is a 1P+N DIN-rail miniature circuit breaker offering 6 kA short-circuit capacity at 230 V. It protects circuits with moderate inrush current against overload and short-circuit, mounting in a single 18 mm module with the neutral on the right.

Selection Notes
The C curve's 5-10 x In instantaneous trip band lets this 20 A breaker ride through the inrush of small motors, transformers or fluorescent ballasts without nuisance tripping. Twenty amps suits sub-distribution for lighting circuits or multiple socket outlets; choose the 25 A or 32 A siblings in this series for circuits with a higher continuous load, or the lower-current variants for individually protected control loads.
