Betagard Residual Current Breaker Operator, Type AC with C characteristic – 5SU1444-1RC63

Product Description

Betagard Residual Current Breaker Operator, Type AC with C Characteristic – 5SU1444-1RC63

The Siemens 5SU1444-1RC63 is a reliable Betagard RCBO (Residual Current Breaker with Overload Protection) designed to provide complete protection for personnel, electrical circuits, and connected equipment in low-voltage power distribution systems. It combines the functionality of an MCB and RCCB in a single compact unit, offering protection against earth leakage, overload, and short-circuit faults.

This model features Type AC residual current detection, suitable for sensing sinusoidal AC leakage currents, and a C-characteristic tripping curve, making it ideal for applications with moderate inrush currents such as lighting systems, distribution circuits, HVAC auxiliaries, and industrial loads.

The 5SU1444-1RC63 is a 4-pole RCBO with 63 A rated current and 100 mA residual current sensitivity, commonly used in commercial buildings, industrial panels, and three-phase distribution systems where enhanced electrical safety and reliable fault protection are required.
