Why Choose the ABB 2CDS381103R0024 Miniature Circuit Breaker?
The ABB 2CDS381103R0024, identified by ABB as the S301P-C2NA, is a high-performance 1P+N miniature circuit breaker from the System pro M compact S300P range. It is engineered to protect industrial and commercial electrical installations against overloads and short circuits while also switching the neutral conductor.
This compact circuit breaker combines a delayed thermal release for overload protection with an electromagnetic release for rapid short-circuit disconnection. ABB features such as an integrated trip indicator, contact-position indication, dual DIN rail release and fail-safe terminals support safe installation, straightforward inspection and efficient maintenance.
Rated at 2 A with a Type C tripping characteristic, the ABB 2CDS381103R0024 is suitable for low-current circuits that may experience moderate starting currents. Its 25 kA rated short-circuit capacity provides robust protection for control equipment, instrumentation, automation systems and other critical circuits.
Key Advantages
- 1P+N configuration disconnects the protected phase and switched neutral together.
- 2 A rated current for low-current industrial and commercial circuits.
- Type C tripping curve accommodates moderate equipment inrush currents.
- 25 kA short-circuit capacity for demanding fault conditions.
- Integrated trip indicator assists with rapid fault diagnosis.
- Fully compatible with ABB System pro M compact accessories.
Key Features
- ABB System pro M compact S300P series.
- S301P-C2NA miniature circuit breaker.
- 1 protected pole plus switched neutral.
- 2 A nominal current rating.
- Type C instantaneous tripping characteristic.
- Thermal overload and electromagnetic short-circuit releases.
- Supply connection possible from the top or bottom.
- Separate terminal openings for cables and busbars.
High-Capacity Protection for Control and Automation Circuits
The ABB S301P-C2NA monitors current flowing through the protected conductor and automatically opens the circuit when an overload persists or a short circuit occurs. Simultaneous neutral switching provides more complete isolation, which is particularly useful during maintenance and fault investigation.
Its Type C response curve is well suited to devices that produce a brief but moderate current surge when energised. This helps prevent unwanted operation while retaining fast disconnection under genuine fault conditions, supporting continuity and safety in professional electrical installations.
Typical Applications
- PLC and industrial automation panels.
- Instrumentation and measurement circuits.
- Machine control systems.
- Signalling and monitoring equipment.
- Commercial distribution boards.
- Transportation and renewable-energy equipment.
