The CNC YCB8-63PV 2P C20 DC500 is a compact and reliable DC miniature circuit breaker designed for photovoltaic, industrial, civil, and communication systems. With a rated current of 20A and operating voltage of DC500V, it provides isolation, overload, and short-circuit protection in heteropolar DC configurations.
This model features a C-type tripping curve, suitable for moderate inrush currents, and supports DIN rail mounting (EN60715). Its modular design, 6kA breaking capacity, and thermomagnetic tripping make it ideal for high-performance DC installations.
Electrical accessories such as auxiliary contact (OF), alarm contact (SD), and shunt release (MX) are available for enhanced monitoring and control. The breaker supports top and bottom wiring, with a terminal capacity of 2.5–25mm² and torque of 3.5 N·m.
