ABB S201P-Z20NA Miniature Circuit Breaker – 1P+N, 20 A, Z Curve
The ABB S201P-Z20NA (ABB order code 2CDS281103R0488) 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 20 A rated current and a Z tripping characteristic (instantaneous trip at 2 to 3 × In), it is suited to semiconductor and electronic circuits that need very fast short-circuit tripping. 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.
- 20 A rated current.
- Z curve tripping characteristic (2 to 3 × 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.
- Electronic equipment, measuring circuits, semiconductor protection and control transformers.
- Distribution boards and control panels.

Frequently Asked Questions
What is the ABB S201P-Z20NA?
The ABB S201P-Z20NA (ABB order code 2CDS281103R0488) is a 20 A, Z 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 Z curve characteristic mean?
A Z curve breaker trips instantaneously at 2 to 3 × In, where In is the rated current. It is intended for semiconductor and electronic circuits that need very fast short-circuit tripping.
What is the rated current?
The rated current is 20 A.
Where is it installed?
It mounts on a 35 mm DIN rail in distribution boards, control panels and machine enclosures.
