Why Choose the ABB S203MT-D16 Miniature Circuit Breaker?
The ABB S203MT-D16 is a robust three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical installations. As part of the specialised ABB S200 MT series, it is suited to industrial, DC and traction-related applications requiring dependable circuit protection and a compact modular format.
This miniature circuit breaker combines a 16 A rated current, D tripping characteristic and 10 kA short-circuit breaking capacity. The D characteristic accommodates high transient starting currents, making the S203MT-D16 particularly suitable for circuits supplying motors, transformers and other inductive equipment with substantial inrush current.
With its three-pole configuration, the S203MT-D16 provides coordinated protection across three conductors and integrates easily into distribution boards, control panels and industrial switchgear. ABB order code 2CDS273445R0161 uniquely identifies this 16 A D-characteristic version of the S203MT range.

Reliable Circuit Protection for High-Inrush Industrial Loads
Miniature circuit breakers such as the ABB S203MT-D16 protect electrical wiring and connected equipment by automatically interrupting the circuit when excessive current occurs. Thermal operation responds to sustained overload conditions, while magnetic operation provides rapid disconnection during severe short-circuit faults, helping protect conductors and equipment against potentially damaging currents.
The D characteristic is particularly useful where equipment produces substantial but legitimate transient currents during energisation. This makes the S203MT-D16 a practical choice for motors, transformers and other inductive loads, while its three-pole construction provides coordinated circuit protection for demanding industrial and specialised electrical systems.
Typical Applications
- Industrial electrical distribution systems.
- DC and traction-related electrical installations.
- Motor circuits with high starting currents.
- Transformer supply and protection circuits.
- Industrial machinery and automation equipment.
- Control panels and electrical switchboards.
- Circuits supplying inductive loads with substantial inrush currents.
