2CSR253101R1325 ABB - DS203 A-B32/0.03

The ABB DS203 A-B32/0.03 is a three-pole Residual Current Circuit Breaker with Overcurrent Protection (RCBO), designed to safeguard electrical circuits from both overload/short-circuit currents and earth fault currents. This device combines the functionality of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) in a single unit. It has a B-curve tripping characteristic, making it suitable for residential and light commercial applications where moderate inrush currents are expected. The rated current is 32A, and the sensitivity to residual current is 0.03A (30mA), providing a high level of protection against electric shock. The DS203 series ensures reliable protection against both overload and short circuits, as well as protection against indirect contact, additional protection against direct contact and fire hazards. It enhances electrical safety by quickly disconnecting the circuit in the event of a fault. This RCBO is ideal for use in distribution boards and consumer units, offering a compact and efficient solution for circuit protection. Its robust design and compliance with international standards ensure long-lasting performance and safety.
