The 5SY4606-7CV is a Siemens miniature circuit breaker (MCB) in the 5SY series, configured 3P+N with a C6 tripping characteristic. That rating places it in the high-breaking-capacity class for a 6 A MCB, sized for industrial panel feeders where prospective fault currents are higher than residential-grade gear can handle. The C6 curve means it trips magnetically between 5× and 10× rated current (30–60 A), so it's a standard choice for general-purpose loads like small motor circuits, contactor coils, and control transformers that see moderate inrush.
The 3P+N width is 4 modules (72 mm at 18 mm per pole). Terminal capacity accepts up to 25 mm² conductor for the line and load side. The C6 rating at 15 kA Icu means this breaker can be used as the incoming protective device for a sub-distribution board or as a feeder MCB in a motor control centre, provided the upstream device is coordinated per IEC 60947-2.
