Why Choose the ABB 2CDS381103R0325 S301P-B32NA Miniature Circuit Breaker?
The ABB 2CDS381103R0325, also known as the S301P-B32NA, is a high-performance 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 compact construction with a high breaking capacity for dependable protection in demanding power-distribution applications.
Featuring a 32 A rated current, a Type B tripping characteristic and a 25 kA short-circuit breaking capacity, the S301P-B32NA is particularly suited to circuits with low starting currents. Typical applications include resistive loads, electric heating, socket circuits, conventional lighting and general-purpose electrical distribution.
The 1P+N configuration enables the protected phase and neutral conductors to be switched together. Its DIN rail mounting format, fail-safe bi-directional screw terminals and clear contact-position indication support straightforward installation, inspection and maintenance within electrical distribution boards, switchboards and industrial control panels.

Reliable Protection for General Electrical Circuits
The ABB S301P-B32NA uses coordinated thermal and electromagnetic release mechanisms to protect connected wiring and equipment. The thermal element responds to sustained overloads, while the magnetic element rapidly disconnects the circuit when a high short-circuit current is detected.
Its Type B operating characteristic provides fast magnetic tripping and is best suited to electrical loads that do not produce significant start-up currents. This makes it a practical choice for resistive equipment, heating circuits, conventional lighting and general power distribution where rapid fault clearance is required.
Typical Applications
- Industrial electrical distribution boards.
- Commercial power-distribution systems.
- Electric heating circuits.
- Resistive electrical loads.
- Socket and outlet circuits.
- Conventional lighting systems.
- Control panels and switchboards.
- Infrastructure and building-services installations.
