Why Choose the ABB DS203 AC-B10/0.03 RCBO?
The ABB DS203 AC-B10/0.03 is a reliable 3-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth fault currents. As part of the ABB DS200 RCBO series, it combines residual current and overcurrent protection in a single DIN rail-mounted device for commercial and industrial electrical installations.
This AC Type RCBO provides protection against the effects of sinusoidal alternating earth fault currents, while its B tripping characteristic is suited to circuits with relatively low inrush currents. The integrated design also provides protection against indirect contact and additional protection against direct contact, helping simplify electrical distribution systems by combining multiple protective functions in one device.
With a rated current of 10 A, a rated residual operating current of 30 mA and a rated short-circuit breaking capacity of 6 kA, the DS203 AC-B10/0.03 provides dependable protection for three-phase circuits. Its compact DIN rail format makes it suitable for distribution boards and control panels where reliable circuit protection and efficient use of panel space are important.
