DSH201 C10 A30 Residual Current Circuit Breaker with Overcurrent Protection

Why Choose the ABB DSH201 C10 A30 RCBO?

The ABB DSH201 C10 A30 is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to provide reliable protection against overloads, short circuits and earth leakage faults. As part of ABB's trusted DSH201 series, it combines miniature circuit breaker and residual current protection into a single DIN rail mounted device, making it ideal for residential and light commercial electrical installations.

Featuring a C tripping characteristic and Type A residual current protection, the DSH201 C10 A30 detects both alternating sinusoidal and pulsating DC residual currents. This makes it suitable for modern electrical installations supplying LED lighting, socket outlets, kitchen appliances, office equipment and other electronic loads.

With a 10 A rated current, 30 mA residual current sensitivity and a 6 kA service breaking capacity, the ABB DSH201 C10 A30 provides dependable protection while maintaining a compact two-module DIN rail design for easy installation.
