Siemens 5SX23 C13 Molded Case Circuit Breaker

Siemens 5SX23 C13 is a three-pole molded-case circuit breaker (MCCB) rated at 10 amps, designed to protect three‑phase circuits in industrial and commercial distribution panels. This device belongs to the 5SX2 family, and it interrupts current automatically when an overload or short circuit occurs, helping prevent wiring damage and equipment failure while providing a manual switching function for service and maintenance. The C13 variant identifies a specific configuration within the 5SX23 lineup, intended for use in panel enclosures that require a compact, reliable MCCB solution for low‑voltage protection. Typical applications include protecting three‑phase feeders and control circuits in panelboards and switchgear assemblies where a 10 A rating offers precise overload protection without nuisance trips. Built to Siemens MCCB standards, it combines solid mechanical construction with predictable trip characteristics, supporting safe operation in demanding environments.
