ABB S301P-C25NA miniature circuit breaker with a 25 A rated current, Type C tripping characteristic, 1P+N configuration and 25 kA ultimate short-circuit breaking capacity for industrial circuit protection.
£75.18
The ABB 2CDS381103R0254, also known as the S301P-C25NA, is a high-performance miniature circuit breaker (MCB) developed to protect industrial electrical installations against overloads and short circuits. Part of the dependable ABB System pro M compact S300P series, it combines a compact design with high fault-breaking performance and compliance with international IEC and UL product standards.
Featuring a 25 A rated current, a Type C tripping characteristic and a rated ultimate short-circuit breaking capacity of 25 kA, the S301P-C25NA is suitable for circuits containing equipment with moderate starting currents. Typical loads include motors, transformers, fluorescent lighting, power supplies and industrial control equipment.
The 1P+N configuration enables the phase and neutral conductors to be switched together, while its compact DIN rail format supports space-efficient installation within control panels and distribution boards. Fail-safe bi-directional screw terminals, an integrated trip indicator and compatibility with ABB System pro M compact accessories help make installation, operation and maintenance straightforward.
The ABB S301P-C25NA uses thermal and electromagnetic release mechanisms to disconnect a circuit when an overload or short circuit occurs. The thermal release responds to sustained overcurrents, while the magnetic release provides rapid interruption when a high fault current is detected.
Its Type C operating characteristic is suitable for equipment that can draw a moderate inrush current during normal start-up. This helps reduce unnecessary tripping while maintaining effective protection for cables, machinery and connected electrical equipment.
