2CSR255180R1327 ABB DS201 K32 A30 RCBO 1P+N 32A Type A 30mA 6kA

Why Choose the ABB DS201 K32 A30 RCBO?

The ABB DS201 K32 A30 is a compact and reliable residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase 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 device for efficient electrical distribution and circuit protection.

This RCBO provides a 32 A rated current, K tripping characteristic and 30 mA Type A residual current sensitivity. Type A residual current protection detects sinusoidal AC and pulsating DC residual currents, while the K characteristic is particularly suited to circuits supplying inductive loads and equipment with higher starting currents.

With a 1P+N configuration and 6 kA short-circuit breaking capacity, the DS201 K32 A30 provides comprehensive protection in a compact DIN-rail format. ABB order code 2CSR255180R1327 identifies this specific 32 A, K-curve, Type A, 30 mA version.

Key Advantages

• Combines residual current, overload and short-circuit protection in one device.
• 32 A rated current for single-phase circuits.
• 30 mA residual current sensitivity for additional protection against electric shock.
• Type A residual current detection for sinusoidal AC and pulsating DC fault currents.
• K tripping characteristic suitable for inductive loads and equipment with elevated starting currents.
• 6 kA short-circuit breaking capacity.
• Compact 1P+N DIN-rail design for distribution boards and control panels.

• ABB DS201 RCBO series.
• 32 A nominal current.
• K-curve tripping characteristic.
• Type A residual current protection.
• 30 mA rated residual operating current.
• 1P+N pole configuration.

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 K32 A30 therefore protects the connected circuit against overload and short-circuit currents while also disconnecting the supply when a 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 electric shock, while the K tripping characteristic makes this model suitable for circuits where equipment can produce relatively high starting currents during normal operation.

Typical Applications

• Single-phase industrial and commercial circuits.
• Motors and inductive electrical loads.
• Equipment with elevated starting currents.
• Machinery and automation control circuits.
• Electrical distribution boards.
• Control panels and light industrial installations.
