Siemens 5SY6101-7 Low-Voltage Circuit Breaker

Siemens 5SY6101-7 is a one-pole miniature circuit breaker (MCB) rated for 230/400 V AC with a short-circuit breaking capacity of 6 kA and a curve C tripping characteristic, specified at a nominal current of 1 A (Inom 1 A). This compact device, with a depth of 70 mm, provides primary overcurrent protection for small distribution circuits in residential and light commercial panels. As part of Siemens' SENTRON 5SY6 family, the 5SY6101-7 is designed to interrupt inrush-prone loads while offering reliable protection for general-purpose applications. The 6 kA breaking capacity and Curve C rating make it suitable for typical domestic and similar-load circuits where moderate inrush currents occur.
