Why Choose the ABB SH203-B32 Miniature Circuit Breaker?
The ABB SH203-B32 is a compact and reliable miniature circuit breaker (MCB) designed to provide overload and short-circuit protection in residential and similar low-voltage electrical installations. As part of the ABB Compact Home SH200 series, it combines a 3-pole configuration, B tripping characteristic and 32 A rated current in a convenient DIN rail-mounted format.
This current-limiting circuit breaker uses two complementary tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanical mechanism for short-circuit protection. The SH200 series is designed for straightforward integration into modular distribution boards and complies with IEC/EN 60898-1 for household, residential and similar electrical installations.
With a rated current of 32 A, a Type B tripping characteristic and a rated short-circuit breaking capacity of 6 kA, the SH203-B32 provides dependable protection for appropriately rated low-voltage circuits. Its Type B characteristic is suitable for loads with relatively low inrush currents, while the three-pole construction enables simultaneous switching and protection across three poles.
Key Advantages
- Reliable overload and short-circuit protection for low-voltage circuits.
- 32 A rated current for appropriately rated electrical circuits.

Reliable Protection for Low-Voltage Circuits
Miniature circuit breakers such as the ABB SH203-B32 automatically disconnect a circuit when excessive current is detected. The delayed thermal tripping mechanism responds to sustained overload conditions, while the electromechanical mechanism provides rapid operation when a short-circuit fault occurs.
The Type B characteristic is commonly suited to circuits with relatively low short-duration starting currents. Combined with the SH200 series' current-limiting design, 32 A rating and three-pole construction, the SH203-B32 provides dependable protection for appropriately designed three-phase and other multi-pole low-voltage circuits.
Typical Applications
- Three-phase low-voltage electrical circuits.
- General building distribution circuits.
- Circuits supplying resistive and relatively low-inrush loads.
- Residential electrical distribution systems.
- Small commercial electrical installations.
- DIN rail-mounted distribution boards and electrical enclosures.
