2CCL562310E1205 ABB - FS401MK-B20/0.03

The FS401MK-B20/0.03 is a sophisticated Residual Current Circuit Breaker with Overcurrent Protection (RCBO) meticulously engineered by ABB. This device provides comprehensive protection against both residual currents and overcurrents, ensuring electrical safety and preventing damage to equipment. It combines the functionality of a residual current device (RCD) and a miniature circuit breaker (MCB) in a single, compact unit. The RCBO is designed to detect earth leakage faults, which can occur when current flows through an unintended path to ground. Upon detection of such a fault, the device swiftly trips, interrupting the circuit and minimizing the risk of electric shock or fire. Additionally, the FS401MK-B20/0.03 offers reliable protection against overloads and short circuits, safeguarding electrical circuits from excessive current flow. Its B-curve tripping characteristic makes it suitable for applications with moderate inrush currents, such as lighting and general-purpose circuits. With a rated current of 20A and a residual current sensitivity of 30mA, this RCBO provides a high level of protection for both people and property. The FS401MK series is known for its robust construction, reliable performance, and compliance with international standards, making it a trusted choice for electrical installations worldwide. This ABB RCBO is ideal for use in residential, commercial, and industrial applications where safety and reliability are paramount.
