The CNC YCB8-63PV 2P C63 DC500 is a robust and compact DC miniature circuit breaker designed for photovoltaic arrays, battery banks, and DC distribution systems. With a rated current of 63A and DC500V operating voltage, it ensures safe and reliable protection against overloads, short circuits, and supports manual isolation of DC circuits.
Its heteropolarity design disconnects both positive and negative lines, enhancing safety in solar and industrial DC installations. The C-type tripping curve accommodates moderate inrush currents from capacitive loads or switching devices.
Built for DIN rail mounting, it features a modular 18mm width per pole, supports top and bottom wiring, and offers optional accessories such as auxiliary contacts (OF), alarm contacts (SD), and shunt release (MX).
Compliant with IEC/EN 60947-2 and EU RoHS, it is suitable for use in residential, commercial, and industrial DC environments, including solar combiner boxes, telecom power systems, and energy storage units.
