£30.53
The ABB 2CDS381001R0105, also known as the S301P-B10, is a high-performance single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the ABB System pro M compact S300P series, it provides dependable protection for demanding industrial and commercial electrical installations.
The S301P-B10 features a B tripping characteristic, making it particularly suitable for circuits with low inrush currents, including lighting, heating equipment, control systems and general electrical loads. Its compact modular design allows efficient installation inside distribution boards, machinery panels and industrial switchboards.
With a rated current of 10 A, an AC breaking capacity of 25 kA and support for operating voltages up to 240/415 V AC, the ABB S301P-B10 delivers reliable circuit protection where high fault interruption performance is required. Its DIN rail mounting format, fail-safe terminals and compatibility with ABB System pro M compact accessories help simplify installation and system expansion.
Miniature circuit breakers automatically disconnect electrical circuits when excessive current results from an overload or short circuit. This helps protect cables, connected equipment and electrical components from overheating, insulation damage and potentially hazardous fault conditions.
The ABB S300P range is developed for industrial applications where high short-circuit performance, dependable operation and compact installation are essential. The S301P-B10 provides a practical protection solution for panel builders, machinery manufacturers, electrical contractors and maintenance engineers requiring reliable performance and compliance with international standards.
