£87.76
The ABB 2CDS381103R0034, also known as the ABB S301P-C3NA, is a premium 1P+N miniature circuit breaker (MCB) from the ABB System pro M compact S300P series. It is engineered to provide dependable protection against overloads and short circuits whilst simultaneously switching the neutral conductor, making it ideal for industrial automation, commercial distribution and OEM machinery.
Designed to meet internationally recognised IEC, EN and UL standards, the S301P-C3NA combines thermal overload and electromagnetic short-circuit protection within a compact modular housing. Its integrated trip indicator, fail-safe terminals and dual DIN rail release simplify installation, maintenance and fault identification in demanding electrical environments.
With a 3 A rated current, a Type C tripping characteristic and a 25 kA short-circuit breaking capacity, the ABB 2CDS381103R0034 is an excellent choice for protecting control circuits, PLC systems, instrumentation and other low-current applications with moderate inrush currents.
The ABB S301P-C3NA provides dependable protection against overloads and short circuits whilst switching both the phase and neutral conductors. This improves electrical isolation, enhances maintenance safety and helps protect sensitive equipment from electrical faults.
Its Type C tripping characteristic makes it particularly suitable for industrial control equipment, PLCs, instrumentation, signalling systems and machinery that generate moderate inrush currents during start-up whilst still requiring rapid fault clearance.
