Meet the Siemens 5SX4102-7 2A 1-Pole 400 V Circuit Breaker—the compact, reliable protection your electrical panels rely on. Designed for single-pole protection in 400 V systems, this Siemens circuit breaker delivers precise 2 A overcurrent protection and quick isolation when faults occur, keeping your critical circuits safe and your operation running smoothly.

  • Part Number: 5SX4102-7
  • Current rating: 2 A
  • Pole configuration: 1-pole
  • Voltage rating: 400 V
  • Brand: Siemens

Why this matters in real-world setups: a precise 2 A protection threshold is ideal for small control circuits, lighting feeders, or instrumentation lines where a higher-rated breaker would be overkill and a lower rating risks nuisance trips. The 1-pole design keeps installation straightforward for single-phase loads, while the 400 V rating broadens compatibility with common industrial and commercial power distributions.

Ideal use cases:

  • Protecting single-phase control circuits in industrial panels
  • Safeguarding lighting feeders in commercial environments
  • Replacing a worn or failed breaker with a trusted Siemens part to restore dependable protection

Practical installation tips:

  • Confirm the circuit load is within the 2 A rating to minimize unwanted trips
  • Reference the Part Number (5SX4102-7) for quick cross-checks during maintenance or replacements
  • Ensure secure connections and adherence to local electrical codes; consult a licensed electrician if needed
