Why Choose the ABB DSE201 M C50 A100 RCBO?
The ABB DSE201 M C50 A100 is a 1P+N electronic residual current circuit breaker with overcurrent protection (eRCBO) designed to protect end-user single-phase circuits against overloads, short circuits and earth fault currents. Part of the ABB DSE201M 10 kA RCBO range, it combines overcurrent and residual current protection in a single device for commercial and industrial low-voltage installations.
This model has a rated current of 50 A, a C tripping characteristic and 100 mA Type A residual current sensitivity. Type A protection detects sinusoidal alternating residual currents and pulsating DC residual currents, supporting reliable earth-fault protection for circuits supplying modern electrical and electronic equipment.
The DSE201 M C50 A100 offers a rated short-circuit breaking capacity of 10 kA and uses a voltage-dependent operating design with an unswitched neutral. Its combination of a 50 A current rating, C characteristic and 100 mA residual sensitivity makes it suitable for higher-current single-phase circuits where dependable overcurrent and earth-fault protection are required.

Combined Overcurrent and Earth-Fault Protection
The ABB DSE201 M C50 A100 combines protection against overload and short-circuit currents with Type A residual current detection. It can detect both sinusoidal alternating and pulsating DC earth fault currents, allowing one protective device to provide multiple protection functions for a single-phase circuit.
Its 50 A C characteristic is suited to higher-current circuits and loads that may exhibit moderate inrush currents during normal operation. Combined with 100 mA residual sensitivity and a 10 kA Icn rating, the DSE201 M C50 A100 is designed for robust commercial and industrial distribution applications where earth-fault and overcurrent protection are required.
Typical Applications
- Commercial electrical distribution boards.
- Industrial low-voltage distribution systems.
- Higher-current single-phase final circuits.
- Equipment and machinery supply circuits.
- Circuits with moderate starting or inrush currents.
- Circuits supplying electrical and electronic equipment.
