Betagard Residual Current Breaker Operator, Type AC with C characteristic – 5SU1644-1RC63

Product Description

Betagard Residual Current Breaker Operator, Type AC with C Characteristic – 5SU1644-1RC63

The Siemens 5SU1644-1RC63 is a high-performance Betagard RCBO (Residual Current Breaker with Overload Protection) designed to provide comprehensive protection for electrical circuits, connected equipment, and personnel in low-voltage distribution systems. It combines the functions of an MCB and RCCB in a single compact device, delivering reliable protection against earth leakage, overload, and short-circuit faults.

This model features Type AC residual current protection, suitable for detecting sinusoidal AC leakage currents, along with a C-characteristic tripping curve, making it ideal for applications with moderate inrush currents such as lighting systems, socket outlets, HVAC equipment, and industrial electrical loads.

The 5SU1644-1RC63 is a 4-pole RCBO with 63 A rated current, widely used in three-phase commercial and industrial distribution boards, where enhanced electrical safety, compact installation, and dependable Siemens performance are essential.
