2CSR274001R1635 ABB - DS204 M AC-B63/0.03

The DS204 M AC-B63/0.03 is a four-pole Residual Current Circuit Breaker with Overcurrent Protection (RCBO) from ABB, designed to provide comprehensive protection against electrical faults. This device combines the functionality of a residual current device (RCD) and a miniature circuit breaker (MCB) in a single unit. It is specifically designed to detect both overcurrents (overloads and short circuits) and residual currents (earth faults). The RCBO offers protection to personnel against electric shock and prevents damage to equipment caused by faulty insulation. With a rated current of 63A and a sensitivity of 0.03A (30mA), it quickly interrupts the circuit in the event of a fault, minimizing the risk of injury or fire. The AC type designation indicates its suitability for detecting AC residual currents. This RCBO is ideal for use in residential, commercial, and industrial applications where reliable protection against both overcurrent and earth fault currents is required. Its compact design allows for easy installation in distribution boards and consumer units, saving space and reducing wiring complexity. The DS204 M AC-B63/0.03 ensures a safe and reliable electrical installation.
