The Siemens 5SU1624-1RC32 is a SENTRON Residual Current Operated Circuit Breaker with Overcurrent Protection (RCBO) that combines overload, short-circuit, and earth leakage protection in a single compact device. Designed with a 2-pole, 4-module configuration, it is rated at 32A and features a C characteristic tripping curve with 300mA Type AC residual current protection, making it suitable for commercial, industrial, and power distribution applications.
This RCBO provides dependable protection against electrical faults, helping safeguard personnel, electrical equipment, and installations from overloads, short circuits, and residual current faults. The C-curve is ideal for circuits with moderate inrush currents, including motors, transformers, and other inductive loads. The Type AC residual current detection is designed for alternating sinusoidal residual currents, making it suitable for standard AC electrical systems.
The 5SU1624-1RC32 features a compact modular design for DIN rail installation, allowing quick integration into distribution boards and control panels. Manufactured to Siemens SENTRON quality standards, it offers high switching performance, long service life, and compliance with international safety standards for reliable operation in demanding environments.
