2CSR252101R1637 ABB DS202 A-K63/0.03 RCBO 2P Type A K 63A 30mA 6kA

Why Choose the ABB DS202 A-K63/0.03 RCBO?

The ABB DS202 A-K63/0.03 is a robust 2-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 Type A RCBO detects sinusoidal AC and pulsating DC residual currents while its K tripping characteristic is particularly suited to circuits with equipment that can produce higher starting or inrush currents, including motors, transformers and auxiliary circuits. The integrated design simplifies installation by combining residual current and miniature circuit-breaker functions in one factory-assembled protective device.

With a rated current of 63 A, rated residual operating current of 30 mA and rated short-circuit breaking capacity of 6 kA, the DS202 A-K63/0.03 provides dependable circuit and additional personal protection. Its two-pole configuration and DIN rail format make it suitable for distribution boards and control panels in demanding electrical installations.
