2CSR274001R1065 ABB DS204MACB60.03 DS204 M AC-B6/0.03 6 A 30 mA 10 kA 4P Type AC RCBO

Why Choose the ABB DS204MACB60.03 RCBO?

The ABB DS204MACB60.03, manufacturer order code 2CSR274001R1065, is a compact and reliable four-pole 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 / DS204 M RCBO series, it combines residual-current and overcurrent protection within a single modular protective device.

The DS204 M AC-B6/0.03 provides a 6 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 a 10 kA short-circuit breaking capacity and four poles, the DS204MACB60.03 is suitable for three-phase electrical distribution applications requiring multi-pole circuit protection. Its modular construction enables straightforward installation within electrical distribution boards and control panels.

Key Advantages

• Combined residual-current and overcurrent protection in a single RCBO.
• 6 A rated current for suitable low-current circuits.
• 30 mA residual operating current for additional protection against electric shock.

Combined Circuit and Residual-Current Protection

RCBOs combine the functions of overcurrent and residual-current protection in one device. The ABB DS204 M AC-B6/0.03 protects connected circuits against excessive current caused by overloads and short circuits while also detecting sinusoidal AC residual currents that can arise from insulation faults and earth leakage.

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 10 kA short-circuit breaking capacity and B-curve overcurrent characteristic, the DS204MACB60.03 provides comprehensive protection for suitable four-pole electrical circuits.

Typical Applications

• Three-phase electrical distribution systems.
• Commercial electrical installations.
• Industrial distribution boards and control panels.
• Circuits requiring combined overload and earth-leakage protection.
• Circuits with resistive or relatively low-inrush loads suited to a B tripping characteristic.
• Applications requiring four-pole circuit protection.
• Final distribution circuits requiring 30 mA residual-current protection.
