2CCL563310E0324 ABB - FS403MK-C32/0.03

The ABB FS403MK-C32/0.03 is a four-pole Residual Current Circuit Breaker with Overcurrent protection (RCBO), designed to safeguard electrical circuits from both overload/short-circuit and earth leakage faults. This device combines the functionalities of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) in a single unit. It has a C-curve tripping characteristic, making it suitable for applications with moderate inrush currents, such as lighting and general power circuits. The rated current is 32A, indicating the maximum current the breaker can handle continuously without tripping under normal conditions. The sensitivity to residual current is 0.03A (30mA), providing a high level of protection against electric shock. This RCBO is designed for DIN rail mounting, ensuring easy installation in standard electrical panels. It offers reliable protection against both overload and short circuits, as well as protection against indirect contact and additional protection against direct contact. The FS403MK series is known for its quality and compliance with international standards, ensuring safe and reliable operation. This device is ideal for use in residential, commercial, and industrial applications where both overcurrent and residual current protection are required.
