ABB 2CDS381103R0517 S301P-K25NA miniature circuit breaker featuring a 25 A rating, Type K tripping characteristic, 1P+N configuration, 240 V AC operating voltage and 25 kA breaking capacity.
£97.76
The ABB 2CDS381103R0517, also designated the S301P-K25NA, is a high-performance miniature circuit breaker (MCB) from the ABB System pro M Compact S300P series. Developed for demanding industrial installations, it provides dependable protection against overloads and short circuits while helping maintain the safe and reliable operation of connected equipment.
Manufactured in accordance with relevant international IEC and UL standards, the S301P-K25NA combines ABB engineering with a compact modular design for straightforward DIN rail installation. Its high short-circuit interruption capability, fail-safe terminal construction and clear switching indication make it a practical choice for industrial control panels, machinery and electrical distribution systems.
Featuring a 25 A rated current, a Type K tripping characteristic, a 1P+N configuration and a 25 kA breaking capacity, the ABB 2CDS381103R0517 is particularly suitable for motors, transformers, solenoids and other inductive loads that can produce elevated starting currents.
Type K miniature circuit breakers are designed for circuits supplying equipment that can draw substantial current when energised. Their instantaneous tripping profile tolerates higher starting currents than more sensitive breaker characteristics, helping prevent unwanted disconnection when motors, transformers and electromagnetic devices start operating.
The ABB S301P-K25NA combines this resistance to nuisance tripping with thermal overload protection and rapid response to genuine short-circuit conditions. This makes it a dependable solution for industrial machinery and automation systems where reliable circuit protection must be balanced with the operating demands of inductive equipment.

The ABB 2CDS381103R0517 protects electrical circuits against overloads and short circuits. Its Type K characteristic makes it particularly suitable for motors, transformers and other inductive loads with high starting currents.
The ABB S301P-K25NA has a rated current of 25 A.
A Type K tripping characteristic is designed to tolerate relatively high start-up currents while continuing to provide rapid protection against genuine short-circuit faults. It is commonly used for motors, transformers, solenoids and similar inductive equipment.
The breaker protects the phase conductor and simultaneously switches the neutral conductor. This provides convenient two-conductor isolation while using one overcurrent-protection mechanism.
The ABB 2CDS381103R0517 has an ultimate short-circuit breaking capacity of 25 kA, making it suitable for demanding installations with high prospective fault currents.
Yes. The S301P-K25NA is designed for installation on a standard DIN rail inside a suitable electrical enclosure or distribution board.
ABB System pro M Compact circuit-protection products are widely specified by electrical engineers, panel builders and machine manufacturers for their dependable operation, compact construction and suitability for demanding industrial applications.
