2CCL563330E0324 ABB - FS403MK-C32/0.3

The ABB FS403MK-C32/0.3 is a sophisticated Residual Current Circuit Breaker with Overcurrent Protection (RCBO), designed to safeguard electrical circuits from both residual current faults and overcurrent situations. This device integrates the functionalities of a residual current device (RCD) and a miniature circuit breaker (MCB) into a single compact unit. It provides comprehensive protection against short circuits, overloads, and earth leakage currents, ensuring the safety of personnel and equipment. The RCBO is particularly suitable for applications where space is limited and a high level of protection is required. With a C-curve tripping characteristic, it is ideal for circuits with moderate inrush currents. The 0.3A sensitivity indicates its ability to detect even small leakage currents, promptly disconnecting the circuit to prevent electrical shocks and fire hazards. This ABB RCBO is a reliable solution for residential, commercial, and industrial electrical installations, offering enhanced safety and peace of mind. Its robust design and compliance with international standards guarantee long-term performance and reliability. It is easy to install and maintain, making it a cost-effective choice for modern electrical protection systems.
