Betagard Residual Current Breaker Operator, Type AC with C characteristic – 5SU1344-7RC40

Product Description

Betagard Residual Current Breaker Operator, Type AC with C Characteristic – 5SU1344-7RC40

The Siemens 5SU1344-7RC40 is a high-quality Betagard Residual Current Breaker Operator (RCBO) designed to provide combined protection against overload, short-circuit, and earth leakage faults in low-voltage electrical distribution systems.

This device features a Type AC residual current detection system, which is suitable for sinusoidal AC leakage currents, and a C-characteristic tripping curve, making it ideal for circuits with moderate inrush currents such as lighting systems, socket outlets, and small motor loads.

Engineered for safety and reliability, it is widely used in residential buildings, commercial complexes, and industrial electrical panels, ensuring continuous protection and system stability.
