£81.46
The ABB 2CDS381103R0044, also known as the ABB S301P-C4NA, is a premium 1P+N miniature circuit breaker (MCB) from the trusted ABB System pro M compact S300P series. Designed for industrial and commercial electrical installations, it provides reliable protection against overloads and short circuits whilst simultaneously switching the neutral conductor for enhanced isolation.
Manufactured to recognised IEC, EN and UL standards, the S301P-C4NA combines thermal overload and magnetic short-circuit protection within a compact modular housing. Integrated trip indication, fail-safe terminals and a dual DIN rail release mechanism simplify installation, servicing and fault identification whilst ensuring dependable long-term operation.
With a 4 A rated current, a Type C tripping characteristic and a 25 kA short-circuit breaking capacity, the ABB 2CDS381103R0044 is ideal for industrial control systems, PLC panels, instrumentation circuits and OEM machinery where moderate inrush currents and high levels of circuit protection are required.
The ABB S301P-C4NA automatically disconnects electrical circuits when overload or short-circuit conditions occur, protecting wiring, control equipment and connected devices from electrical damage. Simultaneous switching of the neutral conductor enhances electrical isolation and improves maintenance safety.
Its Type C tripping characteristic is particularly suitable for automation equipment, PLC systems, instrumentation and machinery with moderate inrush currents, helping minimise nuisance tripping whilst maintaining dependable fault protection.
