2CSR255051R1505 ABB DSE201 B50 AC30 50A 30mA Type AC 6kA RCBO

Why Choose the ABB DSE201 B50 AC30 RCBO?

The ABB DSE201 B50 AC30 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 fault currents. As part of the ABB DSE201 6 kA RCBO series, it combines residual current and overcurrent protection in one device for low-voltage electrical distribution applications.

This model has a rated current of 50 A, a B 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 installations.

With a rated short-circuit breaking capacity of 6 kA, the DSE201 B50 AC30 provides combined circuit and residual current protection for higher-current single-phase final circuits. Its B characteristic is suited to circuits with relatively low starting and inrush currents, making it suitable for general-purpose electrical loads where Type AC residual current protection is appropriate.
