ABB 2CDS381103R0024 S301P-C2NA 1P+N miniature circuit breaker with a 2 A rated current, Type C tripping characteristic and 25 kA short-circuit capacity.
£87.76
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.
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.
