Why Choose the ABB DSE201 C10 A30 RCBO?

The ABB DSE201 C10 A30 is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth fault currents. Part of the ABB DSE201 6 kA RCBO range, it integrates overcurrent and residual-current protection into a single DIN-rail-mounted device for single-phase electrical circuits.

This model combines a 10 A rated current with a C tripping characteristic and Type A residual-current protection. Type A operation provides detection of sinusoidal alternating and pulsating DC residual currents, while the C-curve characteristic is suited to circuits where moderate inrush currents may occur.

With a rated residual operating current of 30 mA and rated short-circuit capacity of 6 kA, the DSE201 C10 A30 provides coordinated earth-fault, overload and short-circuit protection in a compact format. ABB order code 2CSR255151R1104 identifies this specific 10 A, C-curve, Type A, 30 mA configuration.

Key Advantages

  • Combined residual-current and overcurrent protection in one RCBO.
  • 10 A C-curve rating for single-phase circuit protection.
  • 30 mA Type A residual-current sensitivity.
  • 6 kA rated short-circuit capacity.
  • 1P+N configuration for single-phase circuit protection.
  • Type A detection for sinusoidal AC and pulsating DC residual currents.
  • DIN-rail design for straightforward integration into electrical distribution boards.

Key Features

  • ABB DSE201 6 kA RCBO series.
  • 10 A rated current.
  • C tripping characteristic.
  • Type A residual-current protection.
  • 30 mA rated residual operating current.
  • 6 kA rated short-circuit capacity (Icn).
  • 1P+N pole configuration.
  • Combined overload, short-circuit and residual-current protection.
  • Detection of sinusoidal alternating and pulsating DC earth leakage currents.
  • DIN-rail mounting for modular electrical distribution systems.

Combined Overcurrent and Residual-Current Protection

The ABB DSE201 combines the functions of a miniature circuit breaker and residual-current protective device in a single RCBO. It can disconnect the protected circuit in response to overloads, short circuits or qualifying residual currents, helping provide individual circuit protection while reducing the number of separate protective devices required.

The Type A characteristic of the DSE201 C10 A30 enables detection of sinusoidal alternating and pulsating DC residual currents. Together with its 10 A C-curve overcurrent characteristic, 30 mA residual-current sensitivity and 6 kA short-circuit capacity, this configuration provides combined protection for suitable single-phase electrical circuits.

Typical Applications

  • Commercial electrical distribution boards.
  • Single-phase final circuits.
  • Lighting circuits.
  • General electrical equipment circuits.
  • Circuits requiring 30 mA Type A residual-current protection.
  • DIN-rail-mounted electrical control and distribution panels.
