DSH201 C6 A30 Residual Current Circuit Breaker with Overcurrent Protection

Why Choose the ABB DSH201 C6 A30 RCBO?

The ABB DSH201 C6 A30 is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase electrical circuits against overloads, short circuits and earth leakage faults. Combining miniature circuit breaker and residual current protection in a single device, it is ideal for residential and light commercial distribution boards where reliable protection and efficient use of space are essential.

Featuring a C tripping characteristic and Type A residual current protection, the DSH201 C6 A30 detects both alternating sinusoidal and pulsating DC residual currents, making it suitable for modern electrical installations supplying lighting, socket outlets and electronic equipment.

With a 6 A rated current, 30 mA residual current sensitivity and a 6 kA service breaking capacity, the ABB DSH201 C6 A30 provides dependable protection for final circuits while maintaining a compact DIN rail mounted design.
