Siemens 5SX2 201-8 5SX22 1A 2-Pole Circuit Breaker

Siemens 5SX2 201-8 is a two-pole circuit breaker from the 5SX2 family rated for 1 A and designed for 480 V AC systems. Identified in catalogs as 5SX2 201-8, this device is also listed as 5SX22 1A in some references, reflecting its 2-pole, 1-amp configuration within the Siemens line. The 5SX2 family covers multiple 2-pole variants, offering nominal currents from 0.5 A up to 40 A, enabling selection to fit small control circuits up to larger load feeders within 480 V distribution. As a 2-pole device, it protects two conductors in a single package, providing coordinated protection for two-phase or multi-wire 480 V circuits and helping to interrupt fault currents safely. This model is suitable for applications where compact 2-pole protection is required in 480 V electrical installations, such as industrial control panels and equipment enclosures that rely on Siemens protection components. When selecting replacements or spares, verify the exact part number (201-8) to ensure the 1 A rating and 480 V compatibility are maintained, and note that other 5SX2 variants exist with different current ratings within the same family.
