Why Choose the ABB DS203MACC100.03 RCBO?
The ABB DS203MACC100.03, manufacturer type code DS203 M AC-C10/0.03, is a high-performance 3-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth fault currents. As part of the ABB DS200 M RCBO series, it combines overcurrent and residual current protection in a single modular device for electrical distribution applications.
This Type AC RCBO detects sinusoidal alternating residual currents, providing protection against earth leakage faults as well as indirect contact and additional protection against direct contact. Its Type C tripping characteristic makes it suitable for circuits with moderate inrush currents, while the 30 mA residual current sensitivity provides additional protection against electric shock.
With a rated current of 10 A, a 3-pole configuration and a 10 kA rated short-circuit capacity, the DS203 M AC-C10/0.03 provides dependable protection for three-phase circuits. Its DIN-rail-mounted construction enables straightforward integration into modular distribution boards and industrial electrical panels.
