Siemens Circuit Breaker Curve D: Reliable Protection for Motors and Transformers

The Siemens circuit breaker is designed to protect electrical circuits from overloads and short circuits, ensuring a quick and safe response. The curve D, designed for highly inductive loads, prevents unwanted tripping in the presence of high inrush currents typical of:

  • Electric motors

  • Pumps and compressors

  • Transformers

  • Industrial plants and automation panels

The ability to withstand up to 1020 times the nominal current makes it perfect for professional and industrial applications.

Siemens Construction: Quality and Long Life

Designed to last over time, the device guarantees 10,000 mechanical operating cycles, ensuring reliability even in systems subject to frequent operations.

The DIN rail mounting and 4-module format allow for quick installation in domestic, commercial, and industrial electrical panels.
