Why Choose the ABB DS203NC C16 A30 RCBO?
The ABB DS203NC C16 A30 (Product ID: 2CSR256140R1164) is a premium 3P+N Residual Current Circuit Breaker with Overcurrent Protection (RCBO) from ABB's compact DS203NC range. Combining the functions of a miniature circuit breaker and a residual current device in a single unit, it provides comprehensive protection against overloads, short circuits, earth leakage currents, indirect contact and additional protection against direct contact.
Featuring a 16 A rated current, a Type C tripping characteristic and a 30 mA Type A residual current sensitivity, the DS203NC C16 A30 is ideal for three-phase installations supplying commercial buildings, industrial equipment and distribution boards where both overcurrent and earth leakage protection are required.
Its compact four-module design saves valuable panel space while complying with IEC/EN 61009-1 and IEC/EN 61009-2-1. The device offers a 6 kA breaking capacity and is engineered for reliable long-term performance in demanding electrical installations.
