Why Choose the ABB DS203MACB320.03 RCBO?
The ABB DS203MACB320.03 is a high-performance 3-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and sinusoidal AC earth fault currents. Part of the established ABB DS200 / DS203 M series, it integrates residual-current and overcurrent protection into a single DIN-rail mounted device for commercial and industrial three-phase electrical installations.
With a rated current of 32 A, 30 mA residual-current sensitivity and Type B tripping characteristic, the DS203 M AC-B32/0.03 provides dependable protection for circuits requiring sensitive overcurrent operation. Its AC-type residual-current detection responds to sinusoidal alternating earth fault currents, while the 30 mA sensitivity provides additional protection against electric shock.
The DS203MACB320.03 provides a nominal short-circuit breaking capacity of 10 kA and is designed for three-phase electrical distribution applications. ABB supplies this model under order code 2CSR273001R1325, combining robust circuit protection with a modular format suitable for professional distribution boards and control panels.
