ABB 2CSR255080R1324 DS201 C32 AC30 1P+N 32A 10kA RCBO Residual Current Circuit Breaker with Overcurrent Protection

The ABB DS201 C32 AC30 (SKU: 2CSR255080R1324) is a 1P+N RCBO (Residual Current Circuit Breaker with Overcurrent Protection) rated at 32 A with a 10 kA breaking capacity, combining earth leakage and overcurrent protection in a single compact module. Designed for the ABB DS201 series, this RCBO delivers reliable protection for final circuits in residential, commercial, and light industrial control panels, eliminating the need for a separate MCB and RCD.

Technical Specifications

Applications & Use Cases

• Residential distribution boards: Provides combined overcurrent and earth fault protection for 32 A final circuits such as ring mains, cookers, and EV charging points.
• Commercial installations: Ideal for protecting individual circuits in offices, retail units, and light commercial premises where space-saving DIN rail solutions are required.
• Light industrial control panels: Suitable for protecting auxiliary and control circuits against both short-circuit and residual current faults.
• Replacement & retrofits: Direct replacement for existing DS201 series RCBOs in ABB-equipped switchboards, maintaining circuit selectivity with Type C tripping characteristic.

Frequently Asked Questions

What is the difference between the DS201 C32 AC30 and a standard MCB?

The DS201 C32 AC30 is an RCBO — it combines both overcurrent (short-circuit and overload) protection and residual current (earth leakage) protection in one device. A standard MCB provides only overcurrent protection.

What does the "AC" in AC30 mean?

The "AC" designation indicates the residual current type. AC-type RCBOs detect sinusoidal alternating residual currents, making them suitable for standard resistive and inductive AC loads.

What does the "C" tripping characteristic mean?

A Type C tripping characteristic means the RCBO trips on magnetic (instantaneous) overcurrent at 5–10× In. This is appropriate for loads with higher inrush currents such as motors, transformers, and fluorescent lighting.

Is the DS201 C32 AC30 compatible with ABB DIN rail systems?

Yes. The DS201 series is designed for standard 35 mm DIN rail mounting and integrates with ABB's modular consumer unit and distribution board range.
