The CNC YCB7-63N 1P C6 miniature circuit breaker is designed for overcurrent protection in low-voltage electrical systems. With a 6A rated current, C-type tripping curve, and 6kA short-circuit breaking capacity, it ensures safe operation in circuits with moderate inductive loads such as lighting and small appliances.
This 1-pole MCB operates on 230/400V AC, 50/60Hz, and features a thermal-magnetic release mechanism for precise response to overloads and short circuits. It complies with IEC/EN 60898-1 standards and is suitable for residential, commercial, and light industrial environments.
The breaker supports DIN rail mounting, top or bottom wiring, and includes IP20 protection. It can be paired with accessories such as OF, SD, MX, MVMN, and combinations for enhanced functionality.
