Betagard Residual Current Breaker Operator, Type AC with C characteristic – 5SU1444-1RC32

Product Description

Betagard Residual Current Breaker Operator, Type AC with C Characteristic – 5SU1444-1RC32

The Siemens 5SU1444-1RC32 is a high-performance Betagard RCBO (Residual Current Breaker with Overload Protection) designed to provide complete protection for personnel, electrical circuits, and connected equipment in low-voltage distribution systems. It combines the functions of an MCB and RCCB in a single compact device, protecting against earth leakage, overload, and short-circuit faults.

This model features Type AC residual current protection, suitable for detecting 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, HVAC auxiliaries, and inductive loads.

The 5SU1444-1RC32 is a 4-pole RCBO with 32 A rated current and 100 mA residual current sensitivity, commonly used in commercial, industrial, and three-phase distribution applications where enhanced electrical safety and reliable fault protection are required.
