Siemens 5SX23 three‑pole molded‑case circuit breaker is a compact, three‑phase protection device from the Siemens 5SX2 family, designed for industrial panels and distribution systems. It is rated for operation up to 400 V AC and is offered in current ratings including 32 A variants such as 5SX23-C32 and 5SX23-D32, with short‑circuit breaking capacities up to 6 kA at 400 V for these ratings. Trip characteristics include B, C, or D curves to tailor protection for different loads, and the family includes DIN‑rail mountable models for standard industrial enclosures. With 3P construction, it protects all three phases in applications like motor feeders, PLC power circuits, and other three‑phase loads in control panels, delivering reliable overload and short‑circuit protection within a compact footprint.
