Why Choose the ABB DS203NCC32AC300 RCBO?
The ABB DS203NCC32AC300 is a compact 3P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect three-phase electrical circuits against overloads, short circuits and residual earth-fault currents. Part of the ABB DS203NC series, it integrates residual-current and overcurrent protection into a space-saving four-module device.
This RCBO has a rated current of 32 A, a Type C tripping characteristic and a rated residual operating current of 300 mA. Its Type AC residual-current characteristic provides protection against sinusoidal alternating residual currents, while the Type C curve is suited to appropriate circuits where moderate inrush currents can occur.
With a rated voltage of 415 V AC and a rated short-circuit breaking capacity of 6 kA, the DS203NC C32 AC300 provides combined protection for three-phase plus neutral circuits. Its compact DIN-rail construction occupies four modules, helping reduce the panel space required for comprehensive circuit protection.

Reliable Protection for Three-Phase Circuits
RCBOs such as the ABB DS203NCC32AC300 combine overcurrent and residual-current protection within a single modular device. This enables the RCBO to respond to overload and short-circuit conditions while also detecting residual earth-fault currents, providing coordinated protection for suitable three-phase electrical circuits.
The DS203NC series is engineered for compact three-phase distribution systems. Its 3P+N arrangement and four-module construction help conserve valuable switchboard space, while the Type C characteristic makes the DS203NCC32AC300 suitable for appropriate loads that can exhibit moderate starting or inrush currents.
Typical Applications
- Three-phase electrical distribution circuits.
- Commercial and industrial distribution boards.
- Electrical control panels and switchboards.
- Three-phase circuits requiring 3P+N protection.
- Circuits requiring combined overcurrent and residual-current protection.
- Building services and infrastructure electrical systems.
