2CSR253001R1324 ABB DS203 AC-C32/0.03 RCBO 3P AC Type C 32A 30mA 6kA

Why Choose the ABB DS203 AC-C32/0.03 RCBO?

The ABB DS203 AC-C32/0.03 is a dependable 3-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth fault currents. As part of the ABB DS200 RCBO series, it combines residual current and overcurrent protection in a factory-assembled DIN rail device for commercial and industrial electrical installations.

This AC Type RCBO detects sinusoidal alternating residual currents, while its C tripping characteristic is suitable for general-purpose circuits and equipment with moderate starting currents. The DS200 design combines residual current and miniature circuit-breaker functions in one unit, helping simplify installation and wiring while providing dependable protection for individual circuits.

With a rated current of 32 A, a rated residual operating current of 30 mA and a rated short-circuit breaking capacity of 6 kA, the DS203 AC-C32/0.03 provides comprehensive protection for three-phase circuits. Its three-pole configuration and DIN rail format make it suitable for commercial distribution boards, industrial control panels and machinery installations.

Reliable Protection for Three-Phase Circuits

RCBOs combine residual current protection with overload and short-circuit protection in a single device. This allows an individual electrical circuit to be protected against several common fault conditions while reducing the need to install separate residual current and overcurrent protective devices.

The DS203 AC-C32/0.03 uses an AC Type residual current characteristic for sinusoidal alternating earth fault currents and a C tripping characteristic for circuits with moderate starting currents. The ABB DS200 range also incorporates features such as an earth fault indicator and contact-position indication to support straightforward operation and fault identification.

Typical Applications

• Commercial electrical distribution boards.
• Industrial three-phase circuits.
• Machinery and automation control panels.
• General-purpose electrical distribution circuits.
• Equipment with moderate starting currents.
• Installations requiring combined residual current and overcurrent protection.
