Why Choose the ABB S203P-D10 Miniature Circuit Breaker?
The ABB S203P-D10 is a high-performance 3-pole miniature circuit breaker (MCB) from the ABB System pro M compact S200P series. Designed for dependable overload and short-circuit protection, it is suitable for commercial and industrial electrical installations where high breaking capacity and reliable circuit protection are required.
The S200P range uses ABB's current-limiting technology with two tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanical mechanism for short-circuit protection. Its D curve characteristic makes it suitable for circuits with high inrush currents, including transformers, motors, solenoids and other inductive loads.
With a 10 A rated current, 3-pole configuration and 25 kA breaking capacity, the S203P-D10 provides robust protection for three-phase circuits in demanding applications. Its compact DIN rail format supports efficient installation in distribution boards, control panels and automation enclosures.

Reliable Protection for High-Inrush Electrical Circuits
Miniature circuit breakers protect electrical circuits by automatically disconnecting the supply when overloads or short circuits occur. The ABB S203P-D10 combines thermal and magnetic tripping performance to help protect cables, equipment and connected loads from electrical faults.
The D curve characteristic is designed for circuits where high temporary inrush currents are expected during start-up. This makes the S203P-D10 well suited to transformer supplies, motor circuits, industrial control systems and other inductive load applications.
Typical Applications
- Industrial control panels.
- Three-phase power distribution circuits.
- Transformer and inductive load protection.
- Motor control and automation systems.
- Commercial electrical distribution boards.
- OEM machinery and panel building applications.
