Why Choose the ABB SH203-D25 Miniature Circuit Breaker?
The ABB SH203-D25 is a compact and reliable 3-pole miniature circuit breaker (MCB) designed to provide overload and short-circuit protection for low-voltage electrical circuits. As part of the established ABB SH200 MCB series, it combines delayed thermal tripping for overload protection with electromagnetic tripping for rapid protection against short circuits.
With a rated current of 25 A, a Type D tripping characteristic and a rated short-circuit breaking capacity of 6 kA, the SH203-D25 is particularly suitable for circuits supplying equipment that can experience relatively high temporary starting or inrush currents. Its D-curve characteristic helps accommodate these transient current peaks while maintaining effective protection against sustained overloads and short circuits.
The SH203-D25 features a 3-pole configuration, making it suitable for three-phase circuits requiring coordinated switching and overcurrent protection across all three poles. Its compact modular format is designed for DIN-rail installation within distribution boards and electrical control panels. ABB order code 2CDS213001R0251 identifies this specific 25 A D-curve model within the SH200 range.

Reliable Overcurrent Protection for Electrical Installations
Miniature circuit breakers such as the ABB SH203-D25 protect electrical circuits, cables and connected equipment against excessive current. A delayed thermal release responds to sustained overload conditions, while the electromagnetic release provides rapid disconnection when a short circuit occurs.
The Type D characteristic is particularly useful where normal operation can involve substantial momentary starting or inrush currents. Combined with its 25 A rating, 3-pole configuration, 6 kA breaking capacity and compact DIN-rail format, the SH203-D25 provides dependable protection for selected three-phase motor, transformer, machinery and other inductive-load circuits.
Typical Applications
- Three-phase low-voltage electrical circuits.
- Selected motor circuits with high starting currents.
- Transformers and inductive equipment.
- Industrial machinery and equipment circuits.
- Electrical control panels and modular enclosures.
- Three-phase circuits requiring coordinated 3-pole overcurrent protection.
