1. Product Overview

The ABB 1SDA060398R1 Circuit Breaker is a low-voltage protection device used in ABB distribution systems. It protects circuits against overload, short circuit, and leakage currents. When abnormal currents occur, the breaker quickly disconnects the power, protecting both electrical equipment and personnel. The 1SDA060398R1 is suitable for industrial, commercial, and building low-voltage systems and can be combined with auxiliary contacts, contactors, and switch disconnectors for a complete protection solution.
