5SU1646-7FP06

The Siemens 5SU1646-7FP06 is a 4-pole RCBO (Residual Current Circuit Breaker with Overcurrent Protection) designed to provide comprehensive protection against earth leakage currents, short circuits, and overloads. It combines two critical protective functions in one compact device, ensuring both personnel safety and equipment protection.

Featuring a C-characteristic tripping curve, this device is suitable for circuits with moderate inrush currents, such as those caused by inductive loads (e.g., motors, transformers).
