Siemens 5SY4302-7CC SENTRON 3-Pole Miniature Circuit Breaker

Product Overview

The Siemens 5SY4302-7CC is a SENTRON miniature circuit breaker designed for overcurrent protection in electrical distribution and control systems. It provides protection against overloads and short circuits. Its compact design supports installation in industrial control panels and electrical distribution boards.

Protection and Switching

This circuit breaker features a C-type tripping characteristic. It is suitable for circuits with moderate inrush current, including control circuits and selected inductive loads. The thermal-magnetic trip mechanism responds to overload and short-circuit conditions.

The three-pole design allows coordinated protection of three-phase circuits.
