The ABB 2CDS383103R0135, also known as the S303P-B13NA, is a premium miniature circuit breaker (MCB) engineered to protect industrial and commercial electrical installations against overloads and short circuits. As part of the proven ABB S300P System pro M compact series, it combines high fault-breaking performance with compact dimensions, making it an excellent choice for demanding power distribution applications.
Featuring a 3P+N configuration, the S303P-B13NA protects all three phase conductors while incorporating a switched neutral pole. Its Type B tripping characteristic makes it ideal for circuits with low inrush currents, including lighting, resistive loads, commercial distribution systems and general-purpose industrial installations.
With a rated current of 13 A, a maximum operating voltage of 415 V AC and a 25 kA breaking capacity, the ABB S303P-B13NA provides dependable circuit protection while supporting simple DIN rail installation in switchboards, distribution boards and industrial control panels.
The ABB S303P-B13NA automatically disconnects electrical circuits whenever overload or short-circuit conditions occur, helping to protect electrical equipment, wiring and distribution systems while improving operational safety and minimising downtime.
Designed for industrial and commercial installations, the ABB S300P series delivers dependable protection, high fault-breaking performance and long service life. Its Type B characteristic makes it particularly suitable for circuits supplying lighting and resistive loads where rapid fault clearance is essential.
