Siemens 5SX2-204-8 is a two-pole miniature circuit breaker designed for 400 V AC systems, configured with a D4 trip characteristic to protect circuits against overloads and short circuits in distribution panels. This 2-pole device guards two conductors within Siemens’ 5SX2 family and is suitable for commercial and light industrial electrical installations where compact, reliable overcurrent protection is required. The 204-8 designation identifies this specific rating within the 5SX2 lineup, aligning with Siemens’ low‑voltage protection components for standard panelboard applications.
