2CSR255051R1254 ABB DSE201 C25 AC30 25A 30mA Type AC 6kA RCBO

Why Choose the ABB DSE201 C25 AC30 RCBO?

The ABB DSE201 C25 AC30 is a compact 1P+N electronic residual current circuit breaker with overcurrent protection (eRCBO) designed to protect single-phase circuits against overloads, short circuits and earth fault currents. Part of the ABB DSE201 6 kA RCBO range, it combines overcurrent and residual current protection in one device for low-voltage electrical distribution applications.

This model has a rated current of 25 A, a C tripping characteristic and 30 mA Type AC residual current sensitivity. Type AC residual current protection responds to sinusoidal alternating residual currents, while the 30 mA sensitivity provides additional protection against electric shock in appropriate applications.

With a rated short-circuit breaking capacity of 6 kA, the DSE201 C25 AC30 provides combined circuit and residual current protection for single-phase final circuits. Its C characteristic is suited to circuits with moderate starting or inrush currents, making it suitable for a range of general electrical loads.
