Betagard Residual Current Breaker Operator, Type AC with C characteristic – 5SU1344-7RC63

Product Description

Betagard Residual Current Breaker Operator, Type AC with C Characteristic – 5SU1344-7RC63

The Siemens 5SU1344-7RC63 is a high-performance Betagard Residual Current Breaker Operator (RCBO) designed to provide reliable protection against overload, short-circuit, and earth leakage faults in low-voltage electrical distribution systems.

This device combines Type AC residual current protection (for sinusoidal AC leakage currents) with a C-characteristic tripping curve, making it ideal for circuits with moderate inrush currents such as lighting systems, socket outlets, HVAC equipment, and small motor loads.

With a higher rated current of 63A, this RCBO is suitable for demanding applications in residential buildings, commercial complexes, and light industrial distribution systems, ensuring safe and uninterrupted power supply.
