£39.75
The ABB 2CDS381001R0325, also known as the S301P-B32, is a premium single-pole 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 in industrial and commercial electrical installations whilst meeting internationally recognised IEC, UL and CSA standards.
Featuring a Type B tripping characteristic, the S301P-B32 is designed for circuits with predominantly resistive loads or low inrush currents, including lighting, heating systems, socket outlet circuits, distribution boards and control panels. Its fast magnetic response ensures rapid disconnection during fault conditions, helping to safeguard both equipment and wiring.
With a 32 A rated current, a compact single-pole design and a 25 kA rated short-circuit breaking capacity, the ABB S301P-B32 delivers outstanding protection while occupying only one DIN rail module, making it ideal for space-efficient electrical installations.
The ABB S301P-B32 combines thermal overload protection with electromagnetic short-circuit protection to safeguard electrical circuits against faults. Its Type B characteristic provides magnetic tripping between approximately three and five times the rated current, making it particularly suitable for circuits supplying resistive loads and equipment with low inrush currents.
Its compact modular construction, integrated trip indication and fail-safe terminals allow fast installation and dependable long-term operation in commercial buildings, industrial switchboards and OEM equipment.
