Why Choose the ABB DS202MAB500.03 RCBO?
The ABB DS202MAB500.03 is a high-performance 2-pole residual current circuit breaker with overcurrent protection (RCBO) designed to provide combined protection against overloads, short circuits and earth fault currents. Part of the proven ABB DS200 / DS202 M series, it combines residual-current and overcurrent protection within a factory-assembled DIN-rail device for demanding commercial and industrial electrical installations.
With a rated current of 50 A, 30 mA residual-current sensitivity and Type B tripping characteristic, the DS202 M A-B50/0.03 provides dependable protection for final circuits requiring sensitive overcurrent operation. Its Type A residual-current detection responds to sinusoidal alternating and pulsating DC earth fault currents, making it suitable for modern circuits containing electronic equipment.
The DS202MAB500.03 provides a rated short-circuit capacity of 10 kA and is intended for commercial and industrial applications. ABB supplies this model under order code 2CSR272101R1505, with a test pushbutton for functional verification and indication features that assist inspection and fault identification.
