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.
Key Advantages
Combined overload, short-circuit and earth leakage protection.
6 A rated current ideal for lighting and low-load circuits.
30 mA Type A residual current protection.
C curve suitable for circuits with moderate inrush currents.
6 kA rated service breaking capacity.
Compact DIN rail mounted design.
Key Features
ABB DSH201 RCBO series.
1P+N configuration.
6 A rated current.
Type A residual current protection.
30 mA residual operating current.
C tripping characteristic.
DIN rail mounting.
Mechanical endurance of 20,000 operations.
Reliable Combined Protection
The ABB DSH201 C6 A30 continuously monitors both load current and residual current. It disconnects the supply automatically during overloads, short circuits or earth leakage faults, helping protect people, wiring systems and connected equipment from electrical hazards.
Its Type A residual current detection makes it suitable for installations containing electronic equipment capable of producing pulsating DC leakage currents, while the C curve characteristic provides dependable operation on circuits with moderate inrush currents.
