ABB DS201 M C40 A30 Overview

ABB 2CSR275140R1404 is an RCBO designed to provide multiple protection functions within one modular device. The DS201 M combines overcurrent protection against overload and short-circuit conditions with residual current protection.

The product belongs to ABB’s DS201 M range, which includes different rated currents and residual current ratings. ABB’s product table identifies 2CSR275140R1404 as the 40 A, 30 mA version with C characteristic and Type A residual current protection. :contentReference[oaicite:2]{index=2}

1P+N Configuration

The ABB DS201 M C40 A30 uses a 1P+N configuration. The device has two total poles, with one pole protected by the overcurrent protection mechanism and the second pole serving the neutral conductor.

Product data specifies two total poles and one protected pole. The neutral terminal is positioned on the right side of the device according to the referenced technical information. :contentReference[oaicite:3]{index=3}

This configuration is intended for single-phase circuits where the phase conductor requires overcurrent protection and the neutral conductor is switched together with the protected circuit.

40A Rated Current

ABB 2CSR275140R1404 has a rated current of 40 A. This is the nominal current rating of the overcurrent protection section of the RCBO.

The 40 A rating should be coordinated with the connected load, conductor capacity, installation method and other protection devices within the electrical system.

The circuit breaker should not be selected based solely on the nominal load current. The complete electrical installation should be evaluated to determine the appropriate protection rating.

C Tripping Characteristic

The DS201 M C40 A30 uses a C tripping characteristic. ABB’s DS201 M product range includes C-characteristic devices with different rated currents and residual current ratings. :contentReference[oaicite:4]{index=4}

The C characteristic provides a defined instantaneous tripping response for higher current conditions while also providing thermal protection against sustained overload.

It can be used for appropriately designed electrical circuits where the connected load has moderate starting or inrush current characteristics.

Type A Residual Current Protection

ABB 2CSR275140R1404 uses Type A residual current detection. Type A residual current protection is designed to detect sinusoidal AC residual currents as well as pulsating DC residual currents under the applicable operating conditions. :contentReference[oaicite:5]{index=5}

This makes the DS201 M C40 A30 different from an RCBO intended only for Type AC residual currents.

The appropriate residual current type should be selected according to the characteristics of the electrical equipment connected to the protected circuit.

30mA Residual Current Rating

The rated residual operating current of ABB 2CSR275140R1404 is 30 mA. ABB’s product documentation identifies the DS201 M C40 A30 within the 30 mA group of Type A RCBOs. :contentReference[oaicite:6]{index=6}

A 30 mA residual current setting is commonly associated with additional protection against electric shock and leakage-current conditions in suitable end circuits, subject to the requirements of the applicable electrical installation standard.

Overload Protection

The DS201 M C40 A30 incorporates overcurrent protection for the phase pole. The thermal tripping function responds to sustained overload conditions.

When the current remains above the appropriate operating level for a sufficient period, the thermal mechanism operates to interrupt the circuit.

This function protects the electrical circuit against prolonged overcurrent conditions and works together with the instantaneous short-circuit protection.

Short-Circuit Protection

ABB 2CSR275140R1404 also provides protection against short-circuit conditions. The product’s rated short-circuit capacity is specified as 10 kA under the applicable IEC/EN 61009 requirements. :contentReference[oaicite:7]{index=7}

The short-circuit capacity must be considered together with the prospective fault current of the installation.

The actual installation fault level should not exceed the applicable interrupting capacity of the protective device.

Residual Current Protection Function

In addition to overload and short-circuit protection, the DS201 M C40 A30 monitors the electrical circuit for residual current conditions.

When the residual current reaches the applicable 30 mA operating threshold under the specified test conditions, the residual-current mechanism can disconnect the protected circuit.

This integrated protection reduces the need to combine separate overcurrent and residual-current devices for the same protected circuit.

230V AC Rated Voltage

The rated voltage of ABB 2CSR275140R1404 is 230 V AC. Technical product information also specifies a rated insulation voltage of 500 V and a rated impulse withstand voltage of 4 kV. :contentReference[oaicite:8]{index=8}

The operating voltage and electrical network configuration should be verified before installation.

DIN-Rail Mounting

The DS201 M C40 A30 is designed for DIN-rail mounting. Its compact modular housing allows it to be integrated into distribution boards and control cabinets.

The product has a width of approximately 35 mm, corresponding to two DIN modules. The documented dimensions are approximately 35 mm wide, 85 mm high and 69 mm deep. :contentReference[oaicite:9]{index=9}

Compact Modular Construction

The compact construction of ABB 2CSR275140R1404 combines circuit breaker and residual-current protection into one device.

This arrangement can simplify the layout of electrical distribution equipment because separate residual-current protection and overcurrent protection devices are not required for the same circuit when the integrated RCBO is appropriately selected.

Technical Specification Summary

Electrical Protection Functions

ABB 2CSR275140R1404 integrates several protection functions into one modular device. The overcurrent section provides thermal protection against overload and electromagnetic protection against short circuits, while the residual-current section provides Type A earth-leakage protection.

This combination makes the DS201 M C40 A30 a specific protection solution for single-phase circuits where 40 A overcurrent protection and 30 mA Type A residual current protection are required.

Residential Electrical Applications

The DS201 M family is documented for residential, commercial and industrial applications. :contentReference[oaicite:10]{index=10}

In residential installations, a 40 A Type A 30 mA RCBO can be used for appropriately designed final circuits or other single-phase circuits where the electrical system requires this protection configuration.

The final selection must follow the applicable electrical installation rules and the characteristics of the connected load.

Commercial Applications

In commercial electrical distribution systems, ABB 2CSR275140R1404 can be integrated into modular distribution boards where individual circuits require combined overcurrent and residual-current protection.

The 1P+N configuration allows the protected phase and neutral conductors to be controlled together within the same device.

Industrial Applications

The DS201 M C40 A30 can also be used in suitable industrial auxiliary and single-phase circuits.

When applied in an industrial environment, the 40 A current rating, C characteristic, 30 mA residual current rating and Type A detection characteristics should be coordinated with the connected equipment and the complete protection system.

Standards and Compliance

The DS201 M C40 A30 is associated with IEC 61009-1, IEC 61009-2-1, EN 61009-1 and EN 61009-2-1. :contentReference[oaicite:11]{index=11}

ABB’s DS201 M documentation identifies IEC/EN 61009 as the principal standard for the RCBO product family and specifies a 10 kA rated short-circuit capacity for the applicable DS201 M Type A C-characteristic range. :contentReference[oaicite:12]{index=12}

Product Family Variants

ABB’s DS201 M family contains multiple rated-current and residual-current configurations. For the 30 mA Type A C-characteristic range, the documented current ratings include 4 A, 6 A, 10 A, 13 A, 16 A, 20 A, 25 A, 32 A and 40 A. :contentReference[oaicite:13]{index=13}
