2CSR275080R1105 ABB DS201MB10AC30 DS201 M B10 AC30 10 A 30 mA 1P+N Type AC RCBO

Why Choose the ABB DS201MB10AC30 RCBO?

The ABB DS201MB10AC30, manufacturer order code 2CSR275080R1105, is a reliable 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and sinusoidal AC residual currents. As part of the established ABB DS200 / DS201 M RCBO series, it combines residual-current and overcurrent protection within a single modular protective device.

The DS201 M B10 AC30 provides a 10 A rated current, B tripping characteristic and 30 mA rated residual operating current. Its Type AC residual-current characteristic is designed to detect sinusoidal alternating residual currents, while the integrated overcurrent protection safeguards the circuit against overload and short-circuit conditions.

With its 1P+N configuration, the DS201MB10AC30 is suited to single-phase final circuits requiring combined overcurrent and residual-current protection. Its modular construction enables straightforward installation within electrical distribution boards and consumer units.

Key Advantages

• Combined residual-current and overcurrent protection in a single RCBO.
• 10 A rated current for suitable electrical circuits.
• 30 mA residual operating current for additional protection against electric shock.
• Type AC residual-current detection for sinusoidal alternating residual currents.
• B-curve tripping characteristic suitable for circuits with relatively low inrush currents.
• 1P+N configuration for suitable single-phase electrical circuits.

Combined Circuit and Residual-Current Protection

RCBOs combine the functions of overcurrent and residual-current protection in one device. The ABB DS201 M B10 AC30 protects connected circuits against excessive current caused by overloads and short circuits while also detecting sinusoidal AC residual currents associated with earth leakage and insulation faults.

The 30 mA residual-current sensitivity provides additional protection against electric shock, while the Type AC characteristic responds to sinusoidal alternating residual currents. Combined with its B-curve overcurrent characteristic and 1P+N configuration, the DS201MB10AC30 provides comprehensive protection for suitable single-phase final circuits.

Typical Applications

• Single-phase electrical distribution circuits.
• Commercial electrical installations.
• Residential distribution boards and consumer units.
• Circuits requiring combined overload and earth-leakage protection.
• Resistive or relatively low-inrush loads suited to a B tripping characteristic.
• Applications requiring 1P+N circuit protection.
• Final circuits requiring 30 mA residual-current protection.
