ABB S303P-C10 three-pole 10 A miniature circuit breaker with a Type C tripping characteristic and 25 kA breaking capacity for industrial overload and short-circuit protection.
£112.05
The ABB S303P-C10 (Product ID: 2CDS383001R0104) is a high-performance 3-pole miniature circuit breaker (MCB) designed to protect industrial and commercial electrical installations against overloads and short circuits. Part of the established ABB System pro M compact S300P series, it combines dependable circuit protection with a compact modular design for use in distribution boards, switchgear and machinery control panels.
The S303P-C10 features a C tripping characteristic, making it suitable for circuits with moderate switch-on currents. This allows the breaker to accommodate the normal inrush associated with equipment such as small motors, transformers, lighting systems and industrial control devices while responding rapidly to genuine fault conditions.
With a 10 A rated current, three protected poles and a 25 kA short-circuit breaking capacity, the S303P-C10 delivers reliable three-phase protection in installations where high fault interruption performance, service continuity and long-term operational safety are required.
The ABB S303P-C10 uses complementary thermal and electromagnetic releases to protect electrical circuits. The thermal mechanism responds to sustained overloads, while the electromagnetic mechanism provides rapid disconnection during short-circuit conditions, helping to prevent damage to conductors, equipment and connected loads.
Its Type C operating characteristic is widely used for industrial and commercial circuits where moderate inrush currents are expected. This makes the breaker suitable for machinery controls, contactors, transformers, lighting circuits, automation systems and general-purpose three-phase distribution.
