DSN201E C32 A30 Residual Current Circuit Breaker with Overcurrent Protection
ABB DSN201E C32 A30 compact electronic RCBO with a 32 A current rating, C tripping characteristic, Type A 30 mA residual current protection, switched neutral and 6 kA breaking capacity.
Why Choose the ABB DSN201E C32 A30 RCBO?
The ABB DSN201E C32 A30 is a compact 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 reliable ABB DSN201E series, it combines multiple protective functions within a single-module device, helping conserve valuable space in consumer units and electrical distribution boards.
Featuring a C tripping characteristic and Type A residual current protection, the DSN201E C32 A30 detects sinusoidal alternating and pulsating DC residual currents. This makes it suitable for modern circuits supplying appliances, electronic equipment and other loads that may produce pulsating DC earth leakage.
With a rated current of 32 A, a rated residual operating current of 30 mA and a 6 kA short-circuit breaking capacity, the ABB DSN201E C32 A30 provides dependable protection for higher-load final circuits. Its 1P+N configuration, switched neutral and compact DIN rail format support efficient installation and reliable circuit isolation.
Key Advantages
- Combined residual current and overcurrent protection in one device.
- 32 A rated current suitable for higher-load single-phase circuits.
- 30 mA residual current sensitivity for additional protection against electric shock.
- Type A protection detects AC and pulsating DC residual currents.
- 6 kA short-circuit breaking capacity.
- Compact single-module design saves distribution-board space.
Key Features
- ABB DSN201E electronic RCBO series.
- 32 A rated current.
- 1P+N configuration with switched neutral.
- C curve tripping characteristic.
- Type A residual current protection.
- 30 mA rated residual operating current.
- 6 kA breaking capacity.

Reliable Circuit and Earth Leakage Protection
The ABB DSN201E C32 A30 combines the functions of a miniature circuit breaker and residual current device within one compact unit. Its overcurrent protection disconnects the circuit when an overload or short circuit occurs, while its residual current protection responds to potentially hazardous current leakage to earth.
Type A residual current detection makes this RCBO suitable for many contemporary electrical systems containing electronic controls, power supplies and appliances. The switched neutral improves circuit isolation, while the one-module construction enables more protective devices to be installed within a limited panel space.
Typical Applications
- Residential consumer units.
- Commercial distribution boards.
- High-load socket outlet circuits.
- Kitchen and utility appliance circuits.
- Heating and building services equipment.
- Circuits supplying electronic appliances.
