2CSR255180R1325 ABB DS201 B32 A30 RCBO 1P+N 32A Type A 30mA 6kA

Why Choose the ABB DS201 B32 A30 RCBO?

The ABB DS201 B32 A30 is a compact and reliable residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and earth leakage faults. As part of the ABB DS200 / DS201 RCBO range, it combines residual current and overcurrent protection in a single two-module device for efficient electrical distribution and circuit protection.

This RCBO provides a 32 A rated current, B tripping characteristic and 30 mA Type A residual current sensitivity. Type A residual current protection detects sinusoidal AC and pulsating DC residual currents, making the device suitable for modern electrical circuits containing electronic equipment and other loads capable of producing pulsating DC fault currents.

With a 1P+N configuration, 230/240 V AC rated operational voltage and 6 kA rated short-circuit breaking capacity, the DS201 B32 A30 provides comprehensive protection for single-phase circuits while occupying only two DIN modules. ABB order code 2CSR255180R1325 identifies this specific 32 A, B-curve, Type A, 30 mA version.

Combined Residual Current and Overcurrent Protection

RCBOs such as the ABB DS201 combine the functions of a miniature circuit breaker and residual current protection device. The DS201 B32 A30 therefore protects the connected circuit against overload and short-circuit currents while also disconnecting the supply when hazardous residual current to earth is detected.

Its Type A residual current characteristic provides protection against sinusoidal alternating and pulsating direct residual currents. The 30 mA sensitivity supports additional protection against direct contact, while the compact 1P+N construction makes the unit suitable for space-conscious residential, commercial and light industrial distribution systems.

Typical Applications

• Residential single-phase final circuits.
• Commercial electrical distribution boards.
• Socket outlet and power circuits.
• Lighting and general electrical circuits.
• Circuits supplying electronic and single-phase equipment.
• Control panels and light industrial distribution systems.
