2CCL564111E0104 ABB - FS403E-C10/0.03

The FS403E-C10/0.03 is a four-pole Residual Current Circuit Breaker with Overcurrent protection (RCBO) from ABB, designed to provide comprehensive protection against both overload/short-circuit and earth leakage faults. This RCBO combines the functionality of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) in a single compact unit. It has a C-curve tripping characteristic, making it suitable for applications with moderate inrush currents, such as lighting circuits and general-purpose outlets. The rated current is 10A, and the residual current tripping sensitivity is 30mA, offering a high degree of protection against electric shock. It is designed for use in residential, commercial, and industrial applications. The device is DIN rail mountable, simplifying installation in standard distribution boards and consumer units. The FS403E series ensures electrical safety by quickly disconnecting the circuit in the event of an overcurrent or earth leakage fault, preventing damage to equipment and reducing the risk of electrical accidents. Furthermore, it enhances system uptime by minimizing nuisance tripping due to transient overcurrents or earth leakage currents. This RCBO contributes to a safer and more reliable electrical installation.
