Why Choose the ABB S201-D10 Miniature Circuit Breaker?
The ABB S201-D10 is a dependable single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the established ABB System pro M Compact S200 series, this current-limiting circuit breaker provides reliable protection for residential, commercial and industrial electrical installations.
The S201-D10 uses two complementary tripping mechanisms. A delayed thermal mechanism provides overload protection, while an electromechanical mechanism responds rapidly to short-circuit faults. This combination helps protect cables, connected equipment and electrical installations while supporting dependable long-term operation.
With a 10 A rated current, a D curve tripping characteristic and a 6 kA breaking capacity, the ABB S201-D10 is particularly suitable for circuits with high starting currents. Typical loads include transformers, motors, solenoids and other inductive equipment. Its compact single-module format enables straightforward installation on a standard DIN rail.

Reliable Protection for High-Inrush Loads
Miniature circuit breakers automatically disconnect a circuit when excessive current is detected. The ABB S201-D10 provides thermal protection against sustained overloads and fast electromagnetic protection against short-circuit currents, helping to reduce the risk of cable damage and equipment failure.
Its D curve characteristic is designed to tolerate higher temporary starting currents than B or C curve breakers. This makes the S201-D10 suitable for correctly designed circuits supplying equipment such as transformers, motors and electromagnetic devices that may draw substantial current during start-up.
Typical Applications
- Industrial control panels and switchboards.
- Electric motors with high starting currents.
- Transformers and power supplies.
- Solenoids and electromagnetic equipment.
- Commercial and industrial distribution boards.
- OEM machinery and automation equipment.
