ABB S201P-D2NA MCB – 1P+N – D Curve – 2A
ABB S201P-D2NA 1P+N 2 A D curve miniature circuit breaker (one protected pole + switched neutral) from the System pro M compact S200P range. ABB order code 2CDS281103R0021.
ABB S201P-D2NA Miniature Circuit Breaker – 1P+N, 2 A, D Curve
The ABB S201P-D2NA (ABB order code 2CDS281103R0021) is a 1P+N miniature circuit breaker (MCB) from the ABB System pro M compact S200P range. It has one protected pole for the phase conductor and a switched neutral, so phase and neutral are disconnected together when the breaker trips or is switched off.
With a 2 A rated current and a D tripping characteristic (instantaneous trip at 10 to 20 × In), it is suited to loads with high inrush current. Thermal tripping protects against overload and electromagnetic tripping against short circuit.
Key Features
- ABB System pro M compact S200P series.
- 1P+N: one protected pole (phase) plus switched neutral.
- 2 A rated current.
- D curve tripping characteristic (10 to 20 × In).
- 230 V AC rated operational voltage.
- Thermal overload and electromagnetic short-circuit protection.
- 35 mm DIN rail mounting.
- S200P range rated up to 25 kA breaking capacity to IEC/EN 60947-2 (value depends on rating).
- Complies with IEC/EN 60898-1 and IEC/EN 60947-2.
Typical Applications
- Single-phase final circuits where the neutral must be switched with the phase.
- Transformers, motors, welding equipment and capacitive loads.
- Distribution boards and control panels.

Frequently Asked Questions
What is the ABB S201P-D2NA?
The ABB S201P-D2NA (ABB order code 2CDS281103R0021) is a 2 A, D curve, 1P+N miniature circuit breaker from the System pro M compact S200P range.
What does 1P+N mean?
1P+N means one protected pole for the phase conductor plus a switched neutral. Overcurrent protection acts on the phase; the neutral is not protected, but it is switched off together with the phase when the breaker trips or is operated.
What does the D curve characteristic mean?
A D curve breaker trips instantaneously at 10 to 20 × In, where In is the rated current. It is intended for loads with high inrush current.
What is the rated current?
The rated current is 2 A.
Where is it installed?
It mounts on a 35 mm DIN rail in distribution boards, control panels and machine enclosures.
