Betagard Residual Current Breaker Operator, Type AC with C characteristic – 5SU1644-1RC40

Product Description

Betagard Residual Current Breaker Operator, Type AC with C Characteristic – 5SU1644-1RC40

The Siemens 5SU1644-1RC40 is a reliable and high-performance Betagard RCBO (Residual Current Breaker with Overload Protection) designed for complete protection of electrical circuits, connected equipment, and personnel in low-voltage power distribution systems. It combines the functions of an MCB and RCCB in a single compact unit, offering dependable 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 involving moderate inrush currents such as lighting systems, socket circuits, HVAC equipment, and commercial electrical loads.

The 5SU1644-1RC40 is a 4-pole RCBO with 40 A rated current, widely used in three-phase commercial and industrial distribution boards, where enhanced electrical safety and reliable circuit protection are essential.
