£59.49
The ABB 2CDS381103R0165, also known as the S301P-B16NA, is a high-performance miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in industrial and commercial installations. As part of the proven ABB System pro M compact S300P series, it offers dependable circuit protection, high breaking capacity and compliance with international IEC and UL standards.
Featuring a 16 A rated current, a Type B tripping characteristic and a 25 kA short-circuit breaking capacity, the S301P-B16NA is ideal for protecting resistive loads, lighting circuits, control equipment and general-purpose electrical installations. The Type B characteristic provides rapid disconnection during overload conditions, making it well suited to circuits with low inrush currents.
With a 1P+N pole configuration, 240 V AC rated operational voltage and compact DIN rail mounting, the S301P-B16NA is quick to install within electrical distribution boards and industrial control panels. Its fail-safe screw terminals and clear switching indication simplify installation and ongoing maintenance.
The ABB S301P-B16NA automatically disconnects electrical circuits during overload and short-circuit conditions, helping protect electrical wiring, connected equipment and distribution systems. Its Type B tripping characteristic provides fast disconnection for circuits with relatively low inrush currents, making it particularly suitable for lighting and resistive electrical loads.
Designed for demanding industrial environments, the S300P range combines high fault-breaking performance with long-term mechanical reliability, making it a trusted choice for panel builders, OEMs and electrical contractors worldwide.
