2CSR272001R1204 ABB DS202MACC200.03 RCBO 2P C20 Type AC 30 mA 10 kA

Why Choose the ABB DS202MACC200.03 RCBO?

The ABB DS202MACC200.03 is a high-performance 2-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth leakage currents. As part of the ABB DS200 series, it integrates residual current and overcurrent protection within a single modular device, helping simplify electrical distribution and circuit protection.

This RCBO features a Type C tripping characteristic, a 20 A rated current and Type AC residual current protection. Type AC devices are designed to respond to sinusoidal alternating residual currents, while the C-curve characteristic is suitable for circuits with moderate inrush currents.

With a rated residual operating current of 30 mA and a short-circuit capacity of 10 kA, the DS202MACC200.03 provides robust combined protection for electrical circuits where both overcurrent and residual current protection are required. Its two-pole construction provides simultaneous circuit isolation and makes it suitable for a wide range of commercial, industrial and electrical distribution applications.

Combined Circuit and Residual Current Protection

RCBOs such as the ABB DS202 M combine the protective functions of a miniature circuit breaker and residual current device in a single unit. This allows one device to provide protection against overload and short-circuit conditions while also detecting residual currents caused by insulation faults or leakage to earth.

The DS202MACC200.03 uses a Type C overcurrent characteristic together with Type AC residual current detection. Its 30 mA residual current sensitivity provides sensitive earth-leakage protection, while the 10 kA short-circuit capacity makes the device suitable for installations where a higher prospective fault current may be present.

Typical Applications

• Electrical distribution boards.
• Commercial electrical installations.
• Industrial electrical distribution systems.
• Circuits requiring 30 mA Type AC residual current protection.
• Control panels and auxiliary circuits.
• Applications requiring a 10 kA short-circuit capacity.
