Siemens 5SX23 C6 Three Pole Molded Case Circuit Breaker

Siemens 5SX23-C6 is a three-pole molded‑case circuit breaker (MCCB) designed to protect three‑phase power circuits in control panels and switchgear. This Siemens unit is DIN‑rail mountable and carries a 6 A current rating with a C‑curve trip characteristic, suitable for circuits with moderate inrush. It is specified for 400 V AC operation, enabling reliable interruption of fault currents and protection for downstream equipment such as motors, pumps, conveyors, and other three‑phase loads in industrial environments. The compact molded‑case design supports easy integration into standard panel boards, and the three‑pole construction ensures balanced protection across all phases while enabling straightforward replacement or retrofit in service and maintenance tasks. Commonly used in industrial control applications where compact form factor and quick replacement are important, the 5SX23‑C6 provides Siemens‑built protection with clearly identifiable trip action for three‑phase systems.
