Why Choose the ABB 2CDS381103R0467 S301P-K16NA Miniature Circuit Breaker?
The ABB 2CDS381103R0467, also designated the S301P-K16NA, is a high-performance miniature circuit breaker (MCB) from the ABB System pro M Compact S300P series. Engineered for industrial electrical installations, it provides dependable protection against overloads and short circuits while supporting safe and reliable operation in demanding environments.
Manufactured in accordance with international IEC and UL standards, the ABB S301P-K16NA combines a compact modular design with a high short-circuit interruption capability. Its DIN rail mounting arrangement, fail-safe terminals and clear switching position indication help simplify installation, inspection and maintenance within control panels and distribution boards.
Featuring a 16 A rated current, a Type K tripping characteristic, a 1P+N pole configuration and a 25 kA breaking capacity, the ABB 2CDS381103R0467 is particularly suitable for motors, transformers, solenoids and other inductive loads that can produce high starting currents.

Type K Protection for Loads with High Starting Currents
Type K miniature circuit breakers are designed for circuits supplying equipment that can draw a substantial current during start-up. Their tripping profile allows a higher instantaneous current than more sensitive characteristics, helping prevent unwanted disconnection when motors, transformers or electromagnetic devices are energised.
The ABB S301P-K16NA still responds rapidly to genuine short-circuit conditions while providing thermal overload protection during sustained overcurrent events. This combination makes it a practical choice for industrial machinery and automation systems where reliable protection must be balanced with resistance to nuisance tripping.
Typical Applications
- Industrial motor circuits.
- Transformers and control transformers.
- Solenoids, contactors and electromagnetic loads.
- Industrial automation control panels.
- Machine building and OEM equipment.
- Process-control installations.
- Commercial and industrial distribution boards.
- Circuits with elevated switch-on or starting currents.
